Hey Friends,

I’m super excited to announce that I have published a new psychedelics and longevity guide. I wrote this for . You can find the guide on their substack and website.

Read it here

I have been giving lectures about longevity and psychedelics for several months. I most recently gave one at the House of Beautiful Business Conference in May in Athens, and I’m so glad that there are enough recent publications to actually write a guide about the connection between the two.

Check out the guide and tell me what you found interesting.

If you want me to write guides about something else, can you drop your ideas in the comments?

I’d love to hear them.

Xo,

Nina

Seriously, Claude knows how to Code, and once you know how to use Claude…then you know how to code too.

I’ve taught this live class many times now, and every single time, the women leave the room, empowered, excited and ready to keep building with Claude Code

Before my class

My students felt “confused and a bit overwhelmed with what it could do.”

After my class

I recorded my class so you don’t have to wait for the next live cohort.

It’s called Level Up With Claude Code, and it’s the exact class I teach in person.

Grab the Recording

Why I built this

I’m a scientist. I have a PhD, I’ve built four companies, and I still spent months treating Claude like a fancy Google…asking it questions, using it as a thought partner and then just…moving on.

It wasn’t until I took my first Claude Code class and learned what it can really do that my life changed.

Now, I have a full-time intern: eager, occasionally forgetful, and getting better every time I use it. For only $20/month.

That shift, from talking to Claude to building with Claude, is what my Level 1 class teaches.

What’s actually in it

You get the full class, recorded start to finish. IN my live class, I have alot of time to build, so press pause on the video and build alongside the class as we go. I do include some parts where things load slowly or I have to nudge Claude in the right direction, because that’s real, and I want you to see what real looks like.

You’ll learn:

• The 6 ways to actually use Claude: Chat, Cowork, Code (both the desktop app and the terminal), Design, and Science

• How to connect your tools so Claude can see your inbox, your calendar, your notes, and all of the other software tools you use every day

• How to build and schedule a real recurring task. I walk through setting one up live, dictated by voice, start to finish

• How to use Claude Code in the terminal without being scared of it (it just looks like MS-DOS from 1990, and it’s not actually scary…its powerful)

• How to build something playful first. We build a browser game together, because learning can be fun too

• How to create a CLAUDE.md file so you never have to re-explain who you are, how you write, or what you care about, ever again

• A real working example. You build your own, and I demo 1 I built and start building something new

You’ll leave with at least one thing built and one thing automated.

You will build something that actually saves you time by the end of the recording.

Who this is for

This is for the women who’ve been curious about Claude but haven’t had a reason to sit down and actually learn it properly.

You don’t need to know how to code.

You don’t need to understand how large language models work.

I don’t, and I don’t need to, and neither do you.

You just need 90 minutes and a willingness to talk to your computer and tell it what you want to do.

The details

Level Up With Claude Code: the full recorded Level 1 class $99. One-time payment, yours to keep and rewatch. Pause. Play. Build. Go back to it.

Get Instant Access

And if you finish this and want to go further, to build real, complex automations around the actual messy problems in your business, applications are open for the Ladies Who Claude Mastermind a small, three-month cohort with weekly live sessions and office hours with me directly.

Come build something with me.

Love from Lisbon,

Nina

John Krakauer, neuroscientist & neurologist, builds therapeutic games for a living, and he is also one of the most honest skeptics you will hear on what actually helps the brain. In this conversation we get into the messy truth behind brain training, why he does not buy most of the hype, and the one long-term study on dementia that he genuinely cannot explain away.

From there we go somewhere bigger. We talk about why AI keeps looking smarter every year (and why part of that might be us getting a little dumber), why "uploading your brain" belongs in the same bucket as imagining a plane flying backwards, and why the whole idea of longevity might be a misnomer, since most people do not want more years, they want to be young again.

In this episode you will learn:
- How most brain training falls short of what it promises, and the surprising result that made Krakauer pause
- Why language lets us describe impossible things fluently, and what that means for claims about consciousness and brain uploading
- Why medicine reaches for the gadget and skips the hard behavioural work, and why it can be harder to rehabilitate doctors than patients
- What immersive, almost psychedelic digital experiences might offer for healing without any drug involved

Here’s a few stats that made me want to throw my laptop across the room.

Only ~1/3rd of women use AI at work.

There’s a 25% gender gap in adoption between men and women.

Only 9% of women use AI multiple times a day.

Meanwhile every headline out there is telling us AI is about to change how we all work and live.

So I did the only thing that made sense to me, I opened up my living room in Lisbon and started teaching my girlfriends how to use Claude.

And my program, Ladies Who Claude was born.

That was three weeks ago. Since then I’ve taught more than 30 women across group classes and private sessions. Next week I’m moving the class out of the living room and into a larger venue in central lisbon for a class on July 22 from 17:00 - 19:30. Sign up here.

This week’s note is the story of what happened and what my students have built.

Cheers,

Nina

#190: 💻 Ladies Who Claude: What 30 Women Built in Three Weeks

I learned Claude Code through Nick Sarafa’s class back in April and wrote about it here.

It completely changed my life.

In the very literal sense that I don’t start a task anymore, I go to Claude.

Let me repeat that.

I do not start a task. I do not open a spreadsheet. I do not open a software.

I just go to Claude first and tell Claude (with my voice, not typing) what I want to do, then I watch Claude help me do it.

This is the future.

No more software. No more keyboard.

It’s not only a mindset shift but a tooling shift too.

So when I read that women are adopting AI at a fraction of the rate that men are, I couldn’t just be annoyed about it on the internet.

It’s not just that women aren’t adopting AI. This also means they aren’t learning the new tools that support AI. They don’t yet know that soon the keyboard will be obsolete.

And that made me want to bring a room full of actual women together to do something about it.

I’ve always believed women learn differently without men in the room. Something opens up.

People actually say “wait, can you say that again” instead of nodding along and then Googling it later.

So that’s the room I built.

From My Living Room to a Waitlist

Three weeks ago it was me, my laptop, and a handful of friends on my couch. Since then it’s turned into group Zoom classes, hours-long private 1:1 sessions, an in-person workshop planned for next week, and a growing community in a WhatsApp chat.

I’m sending the WhatsApp group a weekly Monday prompt “What are you building this week?” and I’m impressed by every reply of what these ladies are building.

I’ve also started doing 10-minute onboarding calls for every person before the in-person classes so we don’t waste time downloading software during class time.

And now, the next step is my new in-person class at a bigger venue in central Lisbon (Sign up!).

I did not see this coming three weeks ago.

I just wanted to teach my friends.

The Four Ways I Teach Claude

Every session starts the same way because there are four doors into using Claude, and most people only know about one of them.

Chat is the one everyone already knows. Drafting, brainstorming, asking basic questions. Using it as a thought partner.

Cowork is where you start to see the power of AI. This is where you connect your Gmail, your calendar, your Google Drive (and more), then let Claude run light automations and scheduled tasks for you.

Claude Code in the desktop app where you start actually building things. Tools, workflows, small apps, and websites.

Claude Code in the Terminal is the deep end and also the most powerful Claude tool. It’s where Claude was natively built, and it’s the only one with real persistent memory through local project folders.

Almost everyone arrives only knowing Chat, and by the end of class everyone has all 4 options installed and has built their first AI automation.

That’s a win in my book.

The Moments That Made Me SO SO Happy

One of my students, Grace, runs a communications agency across three time zones and told me she resisted Claude “so much” before the class. By the end of our session she said,

“My productivity is insane. Like, I’m quick anyway. But now I’m, like, chaining it. It knows my tone of voice. It’s talking to all my tools. It’s in the Google Drive. It’s in my shoes. Like, it’s just amazing.”

It’s in her inbox, her Drive, her tone of voice, and she said her productivity now feels insane.

That’s Ladies Who Claude in one sentence.

Hayriye, a chef and restaurant owner, opened her session with “I’m a chef, I don’t need AI,” and by the end of class was connecting her restaurant’s Gmail to manage orders.

She almost downloaded a lookalike app with a logo just close enough to Claude’s to fool her, which is a useful thing to watch out for if you’re just getting started. Always download directly from the source, not just the first result in a Google or app store search. (FYI - Claude desktop app can only be downloaded from the Claude.ai/download link.)

One participant created a time-audit and she watched Claude surface that her job search should be her top priority right now, instead of a packed social calendar of Lisbon summer events. (Harsh Claude, but ok).

She also used Claude Code to diagnose why her laptop storage was full, and found close to 150GB of forgotten screen recordings from 2023 she didn’t even know she had.

And then I introduce all my students to my favorite app of all time right now, WisprFlow, the speech-to-text tool I recommend in every single session. I talk at 185 words a minute and type at 80, so the math there isn’t even close. One student clocked in even faster, and asked me, only half joking, why she would ever type again.

Suzy’s Idea Is Now Part of the Program

At my last in-person class on Monday, Suzy (an IFS therapist who came in with a healthy dose of resistance) suggested we end with everyone sharing what they built. I loved it so much that it’s now a permanent part of my program format. Some of the best ideas in this whole program haven’t just come from me, they’ve come from the room.

Nicole, who joined from Barcelona, had already built her own website and brand guide with Claude before ever meeting me.

She mentioned offhand that her WhatsApp group of 27 professional moms was already trading AI tips, things like grocery lists for nannies, school email triage, and multilingual homework help. There’s clearly a “MomBosses Who Claude” workshop waiting to happen, and we’re piloting it.

And there’s Joseph, a private client referred from a ‘Ladies Who Claude’ Alumna, who is a fractional CFO trying to build a slower paced life.

He asked me the question I think everyone secretly wants to ask: has this actually made you more money, or is your life just easier?

My honest answer is both. Claude 100% has made my life easier. I’ve created more hours in the day to enjoy my life - to spend time with friends and do ceramics.

I’ve also made money with Claude. I’ve had Claude help me design guidebooks that I’ve been able to launch within 3 hours, a task that would have taken me hiring a designer and a week’s worth of time before. Claude has helped me to create prospect lists for sales outreach that have landed me podcast sponsorship deals.

And well….*clears throat* I’m launching a movement to empower women with AI because of Claude, and money is flowing in through that too.

Claude helped me to build the entire Ladies Who Claude website and payment pages in one day, making launching this company the easiest launch I’ve ever had.

Mastering Claude is like having a personal assistant with you 24/7. However, you also have to think about Claude the way I’d think about an eager intern, smart, fast, occasionally saving a file in the wrong folder, but completely unbothered when you point it out.

That analogy I took from Nick Sarafa’s class back in April, and I believe it gives people more patience with AI because we shouldn’t expect perfection from AI, just like we don’t expect perfection from humans.

Want to Join Ladies Who Claude?

Next in person class is Wednesday, July 22 at 17:00 - 19:30 in Central Lisbon.

The online program is TBA, but you can sign up for updates on the Ladies Who Claude website through the contact form.

Head to ladieswhoclaude.com to see what’s coming up, or just reply to this email and tell me where you’re stuck with AI.

I read every single message.

🎥 Content of the Week

No book this week, and honestly no show either. The only thing I’ve actually consumed lately is my own AI experiments, so we’re counting that. Besides that I’ve been teaching women how to AI in my living room.

But yesterday, Claude blew my mind. AGAIN.

I built a 20 second teaser trailer for an upcoming guidebook I am launching.

I prompted Claude Fable 5 with this super simple prompt in the terminal:

“I want to create a 20-second teaser trailer for my upcoming guidebook, Longevity and Psychedelics. I can give you the videos of three lectures I gave on the topic. I can also give you the entire text of the guidebook, and I want you to use Higgsfield to create the teaser trailer.”

14 min later, Claude created an animation - gorgeous, colorful, all on its own with no brand direction or creative guidelines.

Then I just had to give it a voiceover file with my own voice, add the Nina’s Notes original jingle, and some small edits. Another 14 min later I had this.

I can’t believe it.

This would have cost me a few hundred dollars, hiring a designer and an animator, and probably 2 weeks of my own time.

⚡️ Check This Out

Claude Science Beta just went live.

I’ve clicked around in it for 10 minutes and I can already tell you this would have saved me at least a year of my PhD.

The first suggested task “Map Recent Literature of the Subfield,” is what most first-year graduate students spend a year doing.

I had to try it.

I asked Claude Science to map the literature of the Psychedelics + Longevity field, which is a small emerging field, and after 20 minutes. It gave me these 2 figures and a list of 42 of the most relevant papers.

This is insane. It’s built for exactly the kind of research-heavy, cite-your-sources, repeatable biology lab bench work that I used to do in my PhD and at my biotech startups.

I’ll report back as I dig deeper.

But already, Wow.

I wish I had this 10 years ago.

In this episode, I sit down with Dr. Frederik Dierick, a family and sports medicine physician turned founder of Pioneer Wellness Group, to explore how hospitality could become one of the most effective (and most overlooked) tools for helping millions of people live longer, healthier lives.

Listen & watch on 🔴YouTube 🟢 Spotify, & 🟣 Apple Podcasts

Frederik makes the case that hotels and resorts are uniquely positioned to deliver science-backed longevity care at scale: guests arrive with time, attention, and motivation that almost never exists in a doctor’s office. We dig into what it actually takes to build a luxury wellness experience that’s grounded in real clinical science (not spa-day wellness theater), why nutrition is the most sensitive topic in medicine, where AI fits in as a health accountability partner, and what it will take to democratize longevity so it’s not just for the ultra-wealthy.

Can a 5-minute brain scan detect dementia years before symptoms?

Jurij Dreo, co-founder and CTO of BrainTrip, draws on 20+ years of EEG research to reveal how brain activity can be measured, interpreted, and used to catch the earliest signs of cognitive decline and dementia — often before they’re visible or irreversible.

In this episode of Nina’s Notes, host Nina Patrick (PhD) and Jurij explore the real potential of EEG technology, why it’s been underused in clinics, and where brain-health diagnostics are headed next. If you care about protecting your memory and measuring your cognitive capital, this one’s for you.

Over the last two weeks, I’ve been teaching AI to my friends in my apartment.

For one friend, we built her social media system, automated her client follow-ups, and started a video research agent, from scratch. She walked in saying she wasn’t tech savvy. She walked out with a running system.

I’ve now done this with five women, one-on-one, in my apartment. And I keep thinking: why is this only happening in my living room?

So I’m opening it up.

This Tuesday, June 30th, I’m running my first online session. 90 minutes, small group, we build your first AI workflow together. €39, 20 spots.

Below you’ll also find three ways to work with me privately if you want something more hands-on.

Why I Started Ladies Who Claude

I kept reading the same article in different formats. In the workplace, men use AI more frequently than women.

Almost two-thirds (64%) of women say they never use AI at work, compared to 55% of men.

And when it comes to AI power users, they’re more likely to be men, 14% of men use AI multiple times a day, versus only 9% of women.

Then I found the student data, and it hit harder. A YouGov survey of UK university students found that only 27% of female students were using AI apps like ChatGPT at least once a week in their studies, compared to 43% of their male peers.

And only 38% of female students said AI was important to their future work, versus 57% of male students.

And it's not a familiarity problem. Harvard Business School research found that women are adopting AI tools at a 25% lower rate than men on average, and when women were given equal access to ChatGPT in a study, they were still 13% less likely to try it.

Access alone isn't closing the gap.

Why? Half of women say that using AI at work feels like cheating. Only 43% of men agree.

Meanwhile, the International Labour Organization found that women's jobs are almost twice as likely to be exposed to AI disruption as men's. 29% of female-dominated occupations face GenAI exposure, compared to 16% of male-dominated ones

So women are less likely to be using the tool, and more likely to have their jobs disrupted by it.

I read all of this and thought: okay, no.

Not on my watch.

What I Did About It

It started with a session in my apartment.

A friend wanted to understand AI, the real, useful, “here’s how this saves you three hours on Tuesday” version.

So I sat down with her, walked her through Claude, built a few things live, and watched her face when it worked.

Then I did it again with three ladies. And again, and again.

Now we have a WhatsApp group. A lot of voice notes at 11pm saying “I just automated this thing.”

Ladies Who Claude is a space for women who want to get better at using AI in real life and real work, without needing to become “AI people.”

This week I ran a full five-hour session with my friend Vika. We set up her entire social media command center in Notion, built an automation that writes and sends client follow-ups, and started a video research agent that scouts content for her reaction posts. She says she is not “tech savvy,” and she left the session with a running system.

⚡️ This Tuesday!

I’m running my first online AI session June 30th at 6pm GMT (10am PST). In 90 minutes, we will build your first workflow together. You will leave the session with something that runs.

Hey friends,

At Longevity Day, Xico Teixeira did a live demo of the biofeedback of your brain when you do a breathwork session.

He led us through three rounds of breathwork while he wore an EEG headband, the one produced by Muse, and displayed his brainwaves on the screen for us to watch.

I interviewed the founder of Muse, Ariel Garten, for the Nina’s Notes podcast last year. Watch the episode here.

If you want to watch your own brain move from the alpha and gamma waves while awake to the theta waves of sleep and deep relaxation, you can grab a Muse headband yourself and train your brain at home.

Use this link and code NINA to get 15% off a Muse headband!

Cheers,

Nina

#187: 🌙 Your Cycle is a Superpower (and a Filter)

Ladies and Gentleman… I’ve been telling a few of my friends how I date in accordance with my menstrual cycle and my girlfriends have looked at me with a raised eyebrow and been like - you what??

This knowledge is really too good to gatekeep and long time readers know that’s never been what Nina’s Notes is about.

So let me school you on the menstrual cycle (Men, don’t stop reading because I know you don’t know this) and how you can use it to improve your dating life and relationships.

What’s Actually Happening in Your Cycle

Listen up. I’ve found a world-class hack here.

If you’re a woman who’s not tracking your cycle, you are missing some extremely useful data pertaining to your own life.

And if you’re in a relationship with a woman, and not paying attention to her cycle, you’re leaving a lot of good evenings on the table.

Let me explain.

The menstrual cycle runs on rotating hormones, primarily estrogen and progesterone, that shape your energy, your mood, your confidence, your social drive and even how attractive you find other people.

It also determines how attractive other people find you.

You may think, Nina, you’re starting to get woo over here but let me stop you. This is well-established endocrinology.

Today, we are going to focus on the two big phases of the women’s cycle.

Get Social In Your Follicular Phase

The follicular phase starts the first day of your period and runs through the first half of your cycle, until ovulation.

Estrogen is rising. And as it climbs, your energy starts to rise with it.

Your social drive is on full blast and many have a desire to be out in the world.

You may want to go out. You might feel a little flirty. You’ll want to put on heels and go out on the town.

Research shows that higher estrogen is associated with increased extroversion, greater risk tolerance, and more positive social engagement.

This is the phase where you actually want to make plans. When putting on the heels and going out sounds like a really good idea.

If you’re actively dating, these are the fun times of the cycle to go out on those first or second dates. Your energy is high, you’re curious, and you’re probably going to have a good time.

Ovulation is When You’re At Your Peak Confidence

Right around the middle of your cycle, estrogen peaks and you get a surge of LH (luteinizing hormone) that triggers ovulation.

This is your peak energy and confidence window.

You’ll be finding people very attractive. And importantly, people will also be attracted to you.

Studies have found that during ovulation, women rate strangers as more attractive.

During ovulation women are perceived by others as more attractive.

Women display more confidence and assertiveness in social settings during this time as well.

Warning: Use this information wisely. I once stopped a man riding a bike during my ovulation phase, he dismounted and asked me on a date with one look. Ladies, we are goddesses here.

There’s even research showing women are more likely to take financial risks and make faster decisions during this window. Proceed with caution.

You’ll notice it if you pay attention. More eye contact. More energy. A slight tendency toward impulsive decisions that feel justified in the moment.

It is a great time to meet someone new, but you also might accidentally fall for someone you would normally swipe left on. Again I’ll say, proceed with caution.

If you’re in a relationship - this is a great time to impress your lady with a night out. Dress up. Take her out. Show her off.

The Luteal Phase: I Hate Everyone

After ovulation, you enter the luteal phase. Estrogen drops. Progesterone rises. The second half of the cycle for many women feels noticeably different.

Lower energy. More introverted. Less interested in socializing. A lower threshold for annoyance.

As I like to put it: I hate everyone.

This is a completely normal, physiological response to shifting hormones. It’s not a character flaw. It’s not you being difficult. It’s progesterone.

Now the worst part of this phase (in my opinion) is the late luteal phase, the days right before your period, when PMS symptoms peak.

Estrogen and progesterone are both low. Your body is winding down, meaning that is not a great time to plan a big night out or a loud restaurant or anything that requires significant social engagement.

🎯 The Filter Hack (This One’s Actually Good)

Now, drum roll please…here’s the dating hack.

If you go out on a date during the luteal phase and you don’t hate that person, that’s actually a really strong signal.

Your tolerance for social stimulation is low. Your energy is down. Your threshold for annoyance is high. Yet you still enjoyed their company?

That person passes the filter.

Compare that to a date during ovulation, when legit ANYONE can seem charming and attractive and the world feels sparkly. Of course you liked them. But how do they hold up when you’re in “I hate everyone” mode?

Track your cycle. Date across phases.

The summary:

• Luteal phase = First dates (The real filter: you won’t be charmed by someone mediocre)

• Follicular = Second dates and beyond (high energy: you’ll actually enjoy it)

• Ovulation = Existing relationship territory only (you might accidentally fall for someone you’d normally swipe left on)

Try this out and see who makes the cut.

👫 If You’re in a Relationship With a Woman

This section is for you.

I’m not going to tell you to memorize a calendar but if you want to be an A+ partner, download a period tracking app and track her damn cycle. And pay attention, because the research here is genuinely useful.

Follicular phase: She has energy. She wants to be out in the world. This is the time for plans. The dinner reservation, the weekend trip, the party you’ve been putting off. Lean into it. She’ll have a good time and so will you.

Ovulation: She’s likely at her most social and most energetic. If you want to try something new together, this is a good window.

Early luteal: Energy starts to dip. A quieter evening starts to look more appealing than a loud bar. Consider a low-key date at home, something that feels special but doesn’t require performance.

Late luteal (pre-period): This is the time to be gentle. Not because she’s fragile, but because her body is working hard and her tolerance for unnecessary stress is legitimately lower. No need to plan anything ambitious. Just be kind and show up.

This is not tiptoeing. It’s about not scheduling a big dinner party the week before her period and then being surprised when it doesn’t go well.

If you work with the biology, everyone wins.

The Science Bit

For anyone who wants the actual mechanism:

Estrogen acts on dopamine and serotonin systems in the brain, which is why higher estrogen is associated with elevated mood, motivation, and social engagement. It also appears to dampen the amygdala’s fear response, which may explain the increased risk tolerance and confidence during the follicular and ovulatory phases.

Progesterone, by contrast, has a calming but also sedating effect, partly through its interaction with GABA receptors. It’s not a villain, but it does shift the nervous system toward rest and withdrawal.

These differences are not subtle. You can feel them in your body, they’re measurable on brain imaging and documented across dozens of studies in behavioral neuroendocrinology.

Your cycle is one of the most powerful modulators of your brain and behavior, cycling through every single month.

Learn it. Use it to your power my goddesses!

Pantheon now on Netflix

Rating: ★★★★★

What if your consciousness could be uploaded to the cloud after you die?

Pantheon is an animated sci-fi drama where a teenage girl starts receiving mysterious messages online, which turn out to be coming from her recently deceased father, whose consciousness was uploaded following an experimental brain scan.

Two companies have cracked the code on “uploaded intelligence,” and they’ve chosen to deploy it in the same way: stripping the uploaded minds of everything but their professional skills so they can keep working, without end, in the afterlife.

Season Two picks up in the wake of a global internet shutdown, with a race to find the one uploaded intelligence that can protect humanity against the other ghosts in the machine.

It has a perfect 100% on Rotten Tomatoes and was criminally cancelled after one season as part of a $400 million tax write-down at AMC. Season Two had already been produced and was pulled before it ever aired. The CEO had abruptly left the company, the network was in chaos, and any platform interested in picking up the show would have had to compensate AMC for the tax hit it had already taken. Thankfully, it eventually found its way to Netflix.

One of the most thought-provoking shows I’ve watched on the intersection of consciousness, identity, and technology. Highly recommended!

This is what cervical mucus looks like under a microscope!

Named after the distinct fern-leaf patterns that appear around ovulation, this is called the Fern Test.

It’s one of the most beautiful things happening in a woman’s body that you’ve never seen.

Cervical mucus is a gatekeeper. It protects from pathogens, fosters healthy bacteria, and helps sperm reach the reproductive tract. It also changes visibly across a woman’s cycle, which is exactly what we see with the fern test.

Wow!

Hey friends,

When I went to Athens in May for The World Beautiful Business Forum, I completely was thrown off of my routine - exercise, eating, everything.

Here I am, a longevity expert, and I couldn’t hold it together over a 5 day conference.

It made me think about what I usually do to stay fit, eat healthy, and sleep properly when I travel. I also thought back to the professionals that I’ve interviewed and I wanted to make a practical list for you, and for myself, the next time I’m at a conference with 12+ hour programming each day.

Here’s what I’ve found. Enjoy!

Cheers,

Nina

#186: 💪🏼 Maintaining Your Routine While You Travel

When we travel, we have many things that throw off your routine - jetlag, early morning meetings, late night social events for work, or staying up late and sleeping in because you’re enjoying your holiday.

I’ve interviewed several professionals about what they do to stay healthy and fit on the road, and how they recover from the grind of constant travel.

Fighting Jet-Lag

Sleep Flying East, Stay Awake Going West

When traveling west, stay awake on the flight. Most Europe-to-US flights take off in the morning, so you’ve already slept. Stay awake on the plane, land in the afternoon in the US, and do your best to stay awake until at least 8pm/9pm local time before going to bed.

The exception to this rule is if you are traveling west and you cross the international date line, for example flying from California to Australia. In this case, sleep on the plane, you will land in the very early morning in Australia, and you’ll need the rest.

Eat Before and After the Flight. Avoid Plane Food.

You want your circadian rhythm in sync with the new timezone, and eating is one of the fastest ways to kickstart that adjustment.

Your first meal after landing should align at a proper mealtime in the local timezone - should be at breakfast, lunch or dinner.

When you arrive at your destination, have a coffee to keep you awake until bedtime. Take melatonin to fall asleep and stay asleep. I take 10mg of melatonin to fall asleep and get a full 7-8 hours of sleep in the new timezone.

One thing I noticed for me, is that the bigger timezone gaps, the easier I find the adjustment. Long-hauls like LA to Sydney, or Lisbon to San Francisco are more manageable than two- or three-hour shifts like Lisbon to Athens, or Vegas to NYC.

Get Off the Plane and Straight To the Gym

This is one of my secret hacks. On a redeye flight from the US west coast to east coast, I usually land at 5am - too early to check in to the hotel, and too early to even meet anyone for breakfast.

So I book an early morning workout class to attend right when I land.

The perks: lockers for your luggage, showers, blow dryers, etc. But more than logistics, it kick-starts your metabolism, gets your muscles moving after hours in a seat and mentally signals to your brain that the flight is over.

You arrive into the day already feeling like yourself.

I also book the earliest morning fitness classes if I wake up too early in the new timezone.

How Formula E World Champion Lucas Di Grassi Fights Jet-Lag

When I interviewed Luca di Grassi, Formula E World Champion, Formula 1 and WEC Le Mans driver, he told me that his jetlag has actually gotten worse with age. And yet, he still has to fully adjust within 2-3 days while on tour driving.

To adjust quickly, he takes probiotics and prebiotics for jet-lag, specifically because travel disrupts the microbiome. Pre-/Probiotics are an easy thing to pack and a genuinely underrated hack.

I’d added my own version to this so that when I arrive somewhere new, I always find a big healthy salad for my first real meal. It’s simple, helps with digestion, and makes you feel like you’re taking care of yourself when everything else feels disrupted.

JJ Virgin’s Travel-as-Lifestyle ToolKit

JJ Virgin, triple board-certified nutrition expert and fitness hall of famer, doesn’t treat travel as an exception to her routine. She told me in our recent interview that she built her routine around the fact that she’s always traveling.

She chooses hotels specifically based on the gym quality. Full stop.

She has a dedicated travel workout plan that divides the body into 4 parts - upper push, upper pull, hip/thigh hinge, power core - so that she can train anywhere and with whatever equipment there is available.

If she can’t make it to the gym - like right before she gets on stage for a talk, she does her hotel room circuit: up-downs, jumping jacks, and air squats. It just takes twenty minutes and really counts.

For timezone adjustment, she takes creatine HCL (not monohydrate). The monohydrate form causes bloating where the HCL form does not and absorbs better at lower doses. She takes four doses on heavy travel days versus her usual one or two doses. She described a recent trip where she went from the Amazon → Egypt → New York → LA and the creatine HCL, she said, is what kept her functional.

On a recent trip to Bali, she stopped over in South Korea specifically to adjust time zones. At the hotel gym, she found people from age 30 to age 100, all in matching PE outfits, just going about their workout like it was the most natural thing in the world. Because, for them it was. And that’s the normalization we are missing.

Whether it’s Lucas adjusting his microbiome between Tokyo and Shanghai, or JJ choosing a hotel by its squat rack, the people who maintain their health while traveling don’t just wing it.

They build systems so that the decision is already made before the jet-lag hits.

You don’t need to be a Formula E driver or a fitness hall of famer to do this.

Pick one thing, like a travel workout you can do in less than 30 minutes (I love Kayla Itsines workouts!), a supplement you pack without thinking, a rule about what you eat when you land, and make it automatic. The routine doesn’t have to survive the trip perfectly, showing up matters the most.

📚 Book of the Week

Brimstone by Callie Hart

Rating: ★★★★★

It’s summer and we’re back with the fairy smut.

Fae-vampire hybrid Queen Saeris Fane and Kingfisher are back for a sequel. The book launches right in, and if you read Quicksilver a while ago (for me over a year ago, it was the BOTW #153).

Quicksilver ends with a massive cliffhanger after Saeris has this wild, otherworldly encounter with the gods…and they expect you to remember all of that when you’re thrown back into this world, trying to remember characters, plots, and chaos.

About 15% in my brain started to settle back down and remember a thing or two.

So my biggest recommendation is to read them back-to-back if you can! Or at least re-read the last chapter of Quicksilver before launching into Brimstone.

Claude often tells me to go to sleep, or to stop working.

As per several Reddit users, they are also getting these suggestions to “get some rest.”

Some people like Claude’s commitment to self-care, while others find it intrusive, annoying or confusing. Because the worst part is that Claude does not seem to know what time it is.

Often I get messages telling me to “get some rest” first thing in the morning when I continue the tread of a conversation.

Good news: Anthropic is looking to fix the quirk.

However, I have to admit, when I run out of tokens it perfectly aligns with lunch or dinner time and a few hours later the tokens reset and I think that is really helpful for my mental health - thanks Claude.

Hey friends,

Last week I curated a stage of 30 speakers covering longevity topics ranging from sleep, breathwork, and women’s health to consciousness and cryopreservation.

It was my first full day event that I’ve curated and it was a huge success, overcapacity with standing room only. Barely anyone left because they didn’t want to give up their seats. Highly engaged audience!

Some feedback that just melted my heart:

“Really brilliant day Nina! You put together such a great event and I loved alllll the talks.”

“Incredible event. I wish I could have stayed the whole day. All of the speakers were so good.”

“Longevity day was the place to be in Lisbon last week.”

“Part of me wishes we could turn back time and do it all over again today, tomorrow, and the day after. Thank you once again for creating such a special experience.”

Cheers,

Nina

#185: The Root Cause of Exhaustion No One is Diagnosing Correctly

I have one colleague that I meet with multiple times a week and every time we open the video chat, the conversation starts with a “this week is AHHHHH” followed by the breakdown of why the days have been insane, the meetings back-to-back, and the impossible volume of work.

This isn’t one bad week or a deadline that got away from him.

This is every week.

This is normal.

Another friend of mine only had time to have a catch-up call with me on her way to the airport because she is flying from Boston to SF multiple times a month now for work.

Another texted me at 9pm telling me she is wrecked.

Meanwhile, my calendar is also full. Podcast interviews, events, writing, ceramics, padel, dance, calls I said yes to. I worry about fitting things in. But I’m not exhausted the way they are.

My calendar has the same density, but something is different.

A packed calendar can lead to exhaustion or it can be fulfilling.

Something is wrong with how we are talking about what occupies our time, and how we feel after that time is spent.

When we look at the calendar, we think we have too many meetings, too much screen time, too much stimulation.

The story we tell ourselves is we’re doing too much. So the answer is subtractive.

The advice is cancel the meetings that don’t need to exist. Do a digital detox. Try a dopamine fast. Block your calendar. Say no more often. Take the vacation you’ve been putting off.

Some of this is good advice. Some of it works for a week.

But none of it solves the thing.

Most of us experience the Sunday Scaries.

The day you’re supposed to be recovering. You rest, you do the slow morning, you take the walk, you don’t check your email. And by Sunday night the dread is there anyway. Monday looms ahead of you. You’re so anxious about the week ahead that you start making the to-do list on Sunday night, just to “get ahead.”

You trade your last hours of the weekend for the illusion of control over the next day coming.

Or you try having an early night mid-week.

You finally have an evening with nothing on it, no work dinner, no call, nothing you said yes to three weeks ago and now regret. You think okay, this is it.

I’ll go to bed at ten. I’ll get the full eight hours. I’ll wake up actually rested for once. The alarm goes off and you’re just as wrecked as every other morning. Because one good night doesn’t undo the twenty before it. You’re exhausted from the last six months, and a single early bedtime can’t pay down that kind of debt.

And vacation doesn’t even seem to fix it. My colleague went to Morocco for his birthday and he didn’t bring the laptop.

He did it right, the actual disconnection. But then the first call we had after he got back, the conversation opened the same way it always does. “This week is AHHHH.”

A week back at his desk and the vacation was already gone. Whatever it refilled, it wasn’t what was actually empty.

So if it’s not too many meetings, and it’s not too little sleep, and it’s not the missing vacation, what is it?

Self-Determination Theory

When I really started to dive into it, I realized that the reason for the exhaustion is not from doing too much. It’s from doing too little of your own choosing.

There’s a framework from psychology called self-determination theory (SDT). It says humans have three basic psychological needs we have to meet to function, and autonomy is one of them. Not autonomy in the grand sense of running your own life. Autonomy in the granular sense: being the one who decided what you’re doing right now.

Chronic low-autonomy environments produce a specific kind of depletion that looks like tiredness but does not respond to rest. You can’t nap your way out of it.

This is also why I’d be just as exhausted as my colleagues if I spent a week doing things I didn’t pick.

The shape of the week matters less than the ownership of what fills your time.

There is an obvious objection here…”But I chose my job. I chose to have kids. I chose this life. So why am I exhausted?”

All true, but choosing the container isn’t the same as choosing what fills it day to day.

You picked the job, but you didn’t pick the 6am meeting.

You picked parenthood, but you didn’t pick that you need to bring homemade muffins to school tomorrow morning.

Macro-autonomy doesn’t substitute for micro-autonomy.

The depletion happens in the small moments. The meeting you didn’t schedule, the muffins you didn’t volunteer for, the Slack message that pulls you off the thing you were actually choosing to do.

Each one is too small to protest but the accumulation is the whole game.

If you’ve been wondering why you can’t seem to rest your way out of this, it’s because the problem was never how much you were doing. It was how little of it was yours.

So, What Actually Refills The Tank?

Side quests, hobbies, and weird small projects that nobody asked you to do. The thing you are doing because you want to, not because it’s on your to do list.

These replenish, because they are self-directed.

This is why the couch fails at being rest. Sitting there scrolling isn’t lazy, your body genuinely needs something, and something with a low cognitive load. The couch/scrolling is a reasonable guess at that.

But the deficit was never inactivity, it’s again the ownership of the tasks.

And unfortunately, scrolling doesn’t supply that ownership. It just supplies cheap dopamine.

Wellness coaches often frame this as a novelty problem. It makes hobbies sound like a brain hack, pull the lever and get the reward.

Essentially saying, “do new things because dopamine.”

But it actually is “do chosen things because your nervous system is starving for evidence that your life is yours.”

Doing side quests is a way to reclaim your autonomy.

Therefore, your hobby, your padel game, the side project you’ve been pushing away for months, they all have a deeper purpose. These aren’t novelty-seeking or dopamine-chasing or productivity-coded self-improvement. They are evidence-gathering for your nervous system.

Your nervous system needs proof that your life belongs to you.

And the only thing that supplies proof is actions that you chose to do actively.

The chosen action is the only thing that shows your nervous system that you are in charge.

That’s why a nap you chose to take can refill the tank, but a vacation your boss prescribed to you doesn’t.

The Biggest Villain is both Work Culture and Wellness Culture

Work culture is the obvious villain in this story and wellness culture is its sidekick.

Both are about optimization, and both promise that if you tune your schedule correctly, you’ll feel better.

Some of this has real science behind it. Meeting timing, morning routines, sleep windows, these things do affect how you feel. The wellness industry didn’t invent the underlying research.

But it took the research and wrapped it in a prescription, and the prescription asks you to perform optimization inside a structure you didn’t design.

Sleep needs are individually determined. Some people are wired to wake at 5am and some at 9am, but the underlying biology is well-established and it’s called your chronotype.

Nonetheless, wellness culture has decided that 4:30am is virtuous and 9:00am is lazy, causing some people to spend years trying to force themselves into a schedule their biology was never going to accept.

But you didn’t choose any of it. You inherited that structure from a wellness influencer, whose body, schedule and life happen to work that way, and now you’re trying to fit yourself into their container.

The core of this problem is actually due to a demanding work culture. Most people don’t have enough autonomy in their schedules to discover what their body actually needs in the first place.

So they fail, and they’ll conclude they lack discipline. Discipline was never the problem. The prescription was wrong for them, and the prescription was never theirs to begin with.

Even worse, many people now again have to force themselves into a schedule that doesn’t fit their biology with the return to office mandates.

After years of working from home, and being more productive by nearly every available metric, millions of people are now back at desks, commuting, sitting through meetings that could have been emails, available in a way that’s mostly about being seen as available.

With the return to office, what changed is the granularity of choice.

When working from home, you decided when to make coffee. When to take a walk. When to step away to think. When to answer Slack and when to leave it.

In the office, those micro-decisions get absorbed by the environment. You don’t choose when you’re interrupted. You don’t choose when to be reachable. You can’t even choose to be in a quiet place in some offices.

Each loss is too small to protest. But each loss of choice wears you down, and the accumulation leads to exhaustion.

Performative availability is more important to companies now than ever. However no one is realizing that this is what causes exhaustion.

The expectation that you’re reachable at all times means your attention is never fully yours, even when no one’s contacting you. You’re holding a slot open. The waiting leads to the feeling of depletion.

Both cultures use the same trick. They give you the appearance of choice inside a structure you didn’t choose. The morning routine looks like authorship. So does the open-plan office with the unlimited PTO. The wrapping is autonomy. The contents are someone else’s blueprint.

The next time you feel the exhaustion that rest doesn’t touch, the question to ask yourself is how much of this week did you actually choose.

Not the job, not the city, not the life, the container is already chosen. Reflect on the hours. The meetings. The morning. Tuesday afternoon between 2 and 4. The thing you’re doing right now.

If the honest answer is “I did not choose much of this,” you don’t need a vacation. You need a side quest. Something small, chosen, slightly pointless and entirely yours.

Your nervous system needs proof that your life still belongs to you.

That’s the antidote to exhaustion. Not less of your time, but more of it spent the way you decided it should be.

📚 Book of the Week

Yellowface by R. F. Kuang

Rating: ★★★★★

I’ve seen this book over and over as a bestseller and definitely waited too long to pick it up.

I didn’t know what to expect, from the title I assumed a white woman impersonating an Asian woman...and while there is some of this going on, it’s more subtle than I originally thought.

The story is about a famous Asian writer Athena, and her supposed best friend and struggling writer June Hayward, the cutthroat publishing industry, cancel culture, and how far a woman will go to obtain the fame and fortune she thought she wanted.

What surprised me most about this book is that I hated all of the main characters. It’s rare to read a book and not relate to a character in some way, empathize with them, or at least find them somewhat endearing.

But this batch of characters, they are all terrible people! June is the worst of them all, but Athena is not innocent either. At moments you really want to jump into the book, grab June and tell her to do the right thing, which does make for an entertaining read.

The novel is fast paced, exhilarating, and I found many evenings when I couldn’t put it down because I really needed to read my characters out of bad situations, only to be surprised when the next situation was worse than the one before.

Great beach read or one for a long plane ride.

Scientists have invented underwear that measures your farts.

Researchers at the University of Maryland built a tiny wearable sensor that attaches to underwear and tracks gas production around the clock, measuring hydrogen, methane, and hydrogen sulphide released by gut microbes as they break down your food.

As lead researcher Professor Brantley Hall put it, we don’t actually know what normal fart production looks like, and without that baseline it’s hard to know when someone’s gas output is truly excessive.

Apparently, the team has found that healthy adults fart an average of 32 times per day - around double the previous estimate.

However their findings also show that daily farts can range from as few as 4 to as many as 59.

This data could help unlock new insights into food intolerances, IBS, and other digestive conditions.

Dr. Axel Schumacher spent 25 years at the forefront of genomics and epigenetic clock research and says your social life is a more powerful longevity biomarker than anything in your bloodwork.

In this episode, he walks through the Social Connectivity Value (SCV): a framework he developed to map your social network, identify the relationships that drain your energy, and turn your social health into a number you can actually track.

What you’ll learn:

• Why loneliness can cost 12–20 years of healthy life (men are hit harder than women) and why the “smoking 15 cigarettes a day” statistic doesn’t change behavior without a way to measure it

• How to build a sociogram using Dunbar’s three layers, assign energy values to every person in your life (including the ones dragging you down), and calculate your SCV score

• Why looking for a romantic partner through your close friends almost never works, and the “super connector” strategy that statistically gives you access to 150 new people from a single introduction

What’s the link between loneliness, AI companions, and living to 150? We get into all of it.

#183: ⚠️ 40% of Women With PMDD Have Suicidal Ideation

Last month was a very very stressful month for me.

I was dealing with two separate situations where I felt responsible for a lot of unhappy people. It was the kind of stress that gets under your skin, has you playing back decisions and conversations, and sticks with you for a while.

And somewhere in the thick of it, in the week before my period, I had a strange thought.

What if I just...disappeared? What would happen to all of this?

Not dramatic. Not scary at the moment.

More like my brain doing a weird stress calculation: if I remove me from the equation, what changes?

It passed quickly. And when my period came, those thoughts lifted completely.

I looked back on it afterward and thought: that was odd. Why did I think that?

So I started asking questions.

What’s Actually Happening In Your Brain During PMS

The week before your period is the late luteal phase. Progesterone and estrogen both start to decline as the body prepares for menstruation.

As women, we all know this…

What we don’t talk about is the cascade of neurochemical events happening in a woman’s brain, that most women have never been told about.

In the late luteal phase when progesterone drops, so does a metabolite called allopregnanolone (ALLO).

ALLO binds to GABA receptors in the brain. GABA is your main inhibitory neurotransmitter. Think of it as the brake pedal.

GABA prevents your nervous system from going into overdrive by blocking specific chemical messages, effectively slowing down brain activity to induce calmness, focus and sleep.

Therefore, you become more reactive, more sensitive to stress, and find it harder to regulate.

At the same time, falling estrogen reduces serotonin and dopamine activity, which are the neurotransmitters most closely associated with mood, happiness and motivation.

The prefrontal cortex, the region responsible for emotional regulation and rational decision-making, becomes less responsive during the luteal phase.

So to recap, in the late luteal phase, we lose the protections of estrogen, progesterone and GABA, which makes every emotion hit harder.

Other people’s moods can feel like your own. The interpersonal friction that you could easily brush off in the follicular phase, like their thoughts are theirs, not mine, now lands like a verdict.

The good news is that this is not a personality flaw.

This is pharmacology happening in your brain. Every. Single. Month.

And no one explains it to you. Until now.

The Thoughts No One Names

Most women know about PMS.

We’ve been told about the usual symptoms. You know, bloating, cramps, irritability, crying at ads for insurance.

What nobody told us, is that for some women, the luteal phase can also bring darker thoughts.

Intrusive ones.

The kind you don’t mention at dinner.

Things like: What if I weren’t here? What if I just stopped?

Not necessarily thoughts of self harm.

More like a morbid ‘what if…?’ that your brain serves up when it’s overwhelmed.

What I learned when I started diving into this is that there is a clinical spectrum in regards to these kinds of thoughts.

Clinicians distinguish between passive suicidal ideation (a wish to disappear or not exist, without intent to act), active ideation, and active planning with intent.

What I experienced, and what I suspect many women experience in the luteal phase under stress, sits somewhere in the gray area before and below the clinical threshold.

It’s not nothing.

And it’s not a crisis.

More like the mind reaching for extreme metaphors when it’s under heavy load.

For women that may experience these darker thoughts, it is possible they could have Premenstrual Dysphoric Disorder (PMDD), which is a severe, chronic form of PMS.

It causes debilitating emotional and physical symptoms during the two weeks before menstruation, which disappear shortly after a period begins.

PMDD is highly disruptive to daily life and requires targeted treatment.

For clarity, this experience is not a one time thing. This is something that happens monthly, for decades of a woman’s life.

And when I dug deeper I found out that researchers have actually looked at this. (T God!)

In a clinical sample of 110 women with confirmed PMDD, 39.1% reported suicidal ideation during the late luteal phase.

That’s nearly 40% of the women with PMDD experiencing suicidal ideation!!!

And no one is talking about it.

The silence problem isn’t the only stigma.

It’s that we’ve built a mental health vocabulary organized solely around crisis, and it skips over everything in the vast gray zone.

Women having these thoughts, can feel disturbed or ashamed, they may not even mention them to anyone.

And the worst part is that they may never learn that the menstrual timing is the cause.

PMS vs. PMDD: Where’s the Line?

PMDD affects around 5.5% of menstruating women.

And you may read that stat and think..oh 5.5% - that is not that bad.

*PAUSE*

Let me elaborate.

There are approximately 1.8 Billion menstruating women globally.

1.8 billion × 5.5% = ~99 million people with PMDD globally

Equalling roughly 100 million women.

100 MILLION!

That’s more than the entire population of the UK and France combined.

That’s more people than the population of Germany.

*picks jaw back up off the floor*

Despite that scale, no mainstream app tracks the darker symptom vocabulary!

And suicidality isn’t even in the diagnostic criteria yet.

grrrrr.

Anyway, what happens in the PMDD brain is fundamentally a neuroendocrinological condition, not a mood disorder in the traditional sense, but a sensitivity condition.

The body produces normal hormonal fluctuations, but the brain responds to them abnormally.

Research published in 2024 showed that people with PMDD don’t just have reduced ALLO during the luteal phase. They have altered sensitivity to ALLO itself.

In these women, normal allopregnanolone levels can paradoxically trigger anxiety and mood disturbances rather than calm. For them, the receptor is calibrated differently.

The key diagnostic signal for PMDD is that symptoms must lift in the follicular phase.

The stark contrast of feeling like a completely different person across the cycle, is not just anecdotal. It is actually the diagnostic data.

For years, many women with PMDD were misdiagnosed with bipolar disorder or borderline personality disorder because no one tracked the cyclical pattern.

Can you believe that?!? We are women, with cycling hormones and no one thought to check the menstrual cycle with symptoms!!!

The International Association for Premenstrual Disorders published a paper in 2025 arguing that suicidality should be formally investigated for inclusion in the PMDD diagnostic criteria, noting that major depressive disorder (MDD) and bipolar II already list it in the DSM-5.

I agree that clearer recognition could prevent exactly this kind of misdiagnosis. And it would help doctors and medical professionals recognize the seriousness of PMDD.

I’ve wondered recently if some of what I’ve experienced in particularly bad luteal phases might qualify as PMDD, or at least sits closer to it than I thought.

It’s possible, but as I thought this, I realized I’m someone who knows what PMDD is. I have a pharmacology background and even with that knowledge, I only learned PMDD existed as an adult.

No one told me when I might have most needed to know.

It Doesn’t Stop at Reproductive Age

…or should I say, and more bad news…

A 2025 review found that 84% of studies showed some association between the menopausal transition and increased suicidality.

One study found that perimenopausal women were seven times more likely to report suicidal thoughts compared to pre- or post-menopausal women.

Suicide rates among women aged 45–55 are notably elevated, which maps almost exactly onto the typical perimenopause window.

Perimenopause involves years of erratic estrogen swings before levels finally settle.

It is not a smooth descent.

And the women most affected are often those who already had significant luteal-phase symptoms earlier in their reproductive years. Which means perimenopause symptoms are a continuation of ones they may not have even known they had.

We talk about hot flashes.

We don’t talk about this.

The Tools Gap

I use Clue to track my cycle.

I like Clue because it has strong data protection. It’s a German company and the women behind it coined the term “FemTech”.

Overall, I’ve found it useful. But when I tried to think about logging something like “had a dark thought this week,” there’s no option for it.

There’s an option for “mood swings.”

There’s an option for “sad.”

There’s a redirect to an external resource if you select anything that sounds serious. That’s it.

They offer 13 emotions which cover a range of feelings, but it is definitely lacking.

And when you go to search for a feeling and it isn’t there, you don’t feel heard.

Clue App I love you! I really do…but reducing feelings to a group of just 13… downplays our emotions.

And women’s feelings are already downplayed 24/7.

I also found a study which confirmed what I suspected, that there is currently no menstrual and mood tracking app with the full capability to accurately capture PMDD symptoms to aid with diagnosis

There’s no normalized, non-alarming language for darker luteal experiences.

No way to log “felt like a burden today” or “I want to disappear” without it feeling like you’re flagging a serious crisis.

So women don’t log it. The pattern never becomes visible. The symptoms are never connected to the calendar.

The irony is that the research is ahead of the tools.

The IAPMD paper calling for suicidality to be included in PMDD diagnostic criteria was published in 2025

Meanwhile, the apps millions of women use to track their cycles still redirect you to a hotline rather than help you track a pattern.

Awareness is the Protection

When I had that dark thought last month, I was genuinely stressed.

But because I’m a scientist who’s a big nerd, I rigorously track my cycle.

And luckily for me, I thought I’m in the luteal phase. I’ve had a brutal few weeks. This is probably just my brain reaching for extreme scenarios because the chemical brake is off. It will pass.

And it did.

The knowledge that this is temporary, that there’s a pharmacological explanation, that it lifts, is itself protective.

This is not a replacement for treatment when treatment is needed.

But it can be a first layer of protection for the potentially millions of women who are in the normal-to-mild range and have no framework for what they’re experiencing.

Tracking your cycle, including the emotional and cognitive symptoms, along with the physical ones, can turn a confusing experience into a pattern.

Once you have a pattern, you can prepare for it. You can take steps and preventative measures with added awareness.

And eventually not feel ambushed by it.

Women deserve that framework.

We should have been given it years ago.

Does This Resonate?

I’ve never written about this before, partly because it’s personal territory and partly because I wasn’t sure how to frame it. I’m still not sure I’ve got it right.

But I think it’s one of the most underserved topics in women’s health, because the cultural permission to talk about it hasn’t been granted yet.

Quick Poll - Would love your answers 🙏🏽

📚 Book of the Week

Big Swiss by Jen Beagin

Rating: ★★★★★

Finally a 5 star book! I’ve been reading some mediocre books this year. Apologies dear readers, but now we have a clear 5 star, no excuses, brilliant read that had me cackling.

Big Swiss is hilarious, awkward, cringe and honest.

The story follows Greta, a transcriptionist for the local sex therapist, who goes by the name of Om, in the small town of Hudson.

Om’s newest client, who Greta knows from her initials FEW, captivates Greta with her traumatic past and sexual repression and she dubs her “Big Swiss”.

One day at the dog park, Greta recognizes Big Swiss’ voice and decides to approach.

Loaded with intimate details of Big Swiss’ life, while Big Swiss is completely unaware, the two become friends and lovers…and chaos ensues.

Pick this one up, you won’t regret it.

The egg chooses.

For centuries, the story of fertilization was framed as a race.

Millions of sperm, one winner, fastest takes all.

Turns out that’s…WRONG!

A study out of Stockholm University found that eggs actively release chemical signals, called chemoattractants, that don’t only attract sperm but also select which ones get through.

Different eggs release different signals.

Different signals attract different sperm.

The egg can even ignore the first sperm to arrive if the chemical compatibility isn’t right.

This study was published in 2020.

It’s now circulating Instagram like breaking news.

Which raises the real question, why did it take six years to go viral?

Why wasn’t this the headline everywhere the moment it was published?

We’ve had this information. We just weren’t talking about it.

Probably because the title of this paper, no offense to the authors, is “Chemical signals from eggs facilitate cryptic female choice in humans”.

Cryptic female choice in humans = what does that even mean!!??

Thank you to the journalists that extracted “the egg chooses” from “cryptic female choice” you’re doing the lords work 🫡

Human sexual reproduction builds an entire narrative around sperm…the speed, the competition, the conquest…making it all sound powerful, while female choice is “cryptic” and that the egg is passive in the process.

When it was the egg calling the shots the whole time!

The egg had the power and scientists just weren’t looking for it. That…in addition to the main article in today’s newsletter…is something worth sitting with.

#181: ✍🏼 Writing Is Thinking. What Happens When We Replace Writing for Dictation?

I’ve been using Wispr Flow for a few weeks. It’s an incredible speech-to-text tool that can clean up the raw transcript into texts, emails, anything you need really.

It’s great for remembering a quick thought, and talking to the LLMs.

But I’m noticing I’m using it more and more to replace the effort of actually writing.

It’s nearly replaced journaling for me.

I still sit at my table with my journal open and start to write, but then by some compulsion, I pick up my phone to dictate into Wispr Flow or Claude instead of taking the time to write out the thoughts slowly.

Even as I got ready to write this article, I was tempted to dictate it into Wispr Flow rather than take the time to type it out.

Wispr Flow also does this terrible thing where they tell you your words per minute in the corner of the desktop app home screen. I speak at 181 words per minute. My typing speed is 61 words per minute. (For reference, “A fast typing speed is generally anything above 70 words per minute (WPM)...nowhere close to our speaking speed.)

I speak at 3x my typing speed, and that number glares at me every time I open the Wispr Flow desktop app.

No wonder it seems daunting to stare at a blank Google Doc and think - this is going to take a while.

But, that’s the point.

Writing Is the Cognitive Work

Writing is the art of slowing down.

There is a friction that happens when you write.

You have to choose the next word intentionally.

Even in a stream of consciousness you’re still making micro-decisions, selecting, pausing, reconsidering.

When I dictate, a lot of what comes out sounds like this:

“I guess what I mean is probably…” “I’m thinking, okay, so the thing is...”

Those filler phrases rarely make it into written work because writing focuses you to skip past the throat-clearing and get to the actual thought.

The choosing of the word, the pausing and reflecting while writing is part of the craft.

It is not inefficiency, it’s where clarification happens. It’s where good explanations are made and practiced.

You often don’t know what you think until you’ve done the writing.

Who Wrote This Message?

Are we losing this layer of cognitive work as we all start to leverage the speech-to-text?

Then instead of doing the cognitive work ourselves, we leverage an LLM to make sense of what we mean, and then we send it off to our friends, family and colleagues with barely an edit.

We’re already getting such a flood of AI-slop to read on the internet, and now this is coming into almost every form of online written communications - not just blog posts, newsletters, news media and bad LinkedIn posts - It’s coming into text messages and Instagram messages where people have set up AI agents to reply back to their messages for them.

Forcing us to ask ourselves “Was this written by AI?” and analyze the messages we get.

I’ve definitely found myself wondering if this sort of over-polished, neutral, bloodless prose that sounds like nobody, is actually how my colleagues email people?

Was this text truly written by my friend? Are they too busy, or too lazy, to simply type a quick response?

However there are advantages to using speech to text. For myself, I can get the raw, unedited tone of my voice, the tangents (or ADHD subplots…) and the uncertainties. Speech-to-text can put a spotlight on my tone in the way I think out loud.

I often forget what I said but luckily Wispr Flow keeps the history, so I can go search for it later.

But is this harming my memory?

What the Neuroscience Says About Writing vs. Dictation

There is solid research that shows that information that you produce yourself (the generation effect), even if it’s just restating something you learned in your own words, is retained significantly better than information that you passively receive.

Writing forces that generation.

Dictation, especially if you know it will be cleaned up for you, is much more passive.

You are outputting content, but you aren’t necessarily constructing or crafting it.

When you write, you have to hold an idea in your working memory. When you hold it there, you are evaluating and revising it before it hits the page. Then you do more editing and revising.

This is a metabolically expensive task, and it is cognitively generative.

Speaking and dictation externalize that mental load. It flows through you which feels easier and that’s because it is easier. It is metabolically and cognitively easier.

However, that hard work of compression, understanding and evaluation doesn’t happen.

Or…it gets outsourced to an LLM for editing and clean-up which makes us all sound the same anyway.

There is also research suggesting that the act of writing doesn’t just record an idea, it actually changes the idea.

There is the constraint of needing to convey your message linearly, and having to commit to one word before the next, that forces a resolution of the idea that speaking doesn’t.

You can talk in circles for 20 minutes and feel like you’ve thought something through.

However if you try to read a transcript of that circular talking, you’ll be confused and probably bored.

Now if you instead spend that 20 minutes trying to write down the thought, you’d probably expose the holes in your thinking faster, and come to a consolidation of the idea.

It’s also worth examining that there is a difference between retrieving a thought or idea - which we can do through dictation, and then forming a thought or idea.

Writing, at its best, forms the thought into an idea that can then be communicated clearly.

And that effort of formation of the thought to an idea, expending the cognitive energy to do so, seems to me like a way to sustain and improve our cognitive health.

To be fair, there are real advantages to dictation.

I’m not going to tell you to delete Wispr Flow. I’m still using it.

But, I am going to be more intentional about when I reach for it. Quick thoughts, voice memos, talking to an LLM, fine.

When I sit down to actually think something through, I want to feel that friction. The slowness isn’t the bug. It’s where the thinking happens.

This newsletter took me longer to write than it would have to dictate. I noticed every time I wanted to pick up my phone.

I left the holes in my thinking exposed until I had to actually resolve them on the page and I think I understand what I believe about dictation vs writing now, in a way I wouldn’t have if I’d just talked it out.

Maybe that’s the test worth applying: Is this something I want to retrieve, or something I want to form?

If it’s the latter, put the phone down. Open the doc. Choose the next word intentionally.

Your brain will thank you…and possibly even remember it.

📚 Book of the Week

The Deserters by Mathias Enard

Rating: ★★★☆☆

The Deserters follows two parallel timelines, one present-day and one set during a past war, for most of the book though you’re waiting for the moment they converge. That anticipation is either the novel’s greatest tension or its greatest frustration, depending on your tolerance for ambiguity. For me, it was the latter.

The war-era timeline carries a mysterious soldier at its center and I kept reading to find out who he was.

SPOILER ALERT!

That question never gets answered. The two storylines never fully meet, and if you’re the kind of reader who needs narrative resolution, that absence will leave you genuinely unsatisfied.

That said, both timelines are emotionally rich. The writing captures pain, love, and the particular sorrow of lives shaped and broken by conflict. There’s real craft here and clearly a lot of intention behind the structure.

But intention isn’t always enough. A dual timeline story lives or dies by the payoff, and this one left me hanging. I finished it respecting the ambition of the author more than I enjoyed the experience.

Oh dear lord.

California startup Span is partnering with Nvidia to turn your home into a mini data center.

The average household uses only about 42% of its allotted power. Span wants to fill that gap by installing “nodes” packed with 16 Nvidia GPUs and roughly $500k worth of hardware, then use that spare electricity to run AI compute.

In exchange, homeowners get their energy and internet bills subsidized.

The startup has outfitted one home so far, with around 100 more rolling out in a pilot program later this year.

Whether you’d actually want a $500k server rack humming away in your spare bedroom is a different question entirely.

In this episode, I sit down with Dr. Katrin Dreissigacker, a plastic surgeon turned longevity architect and founder of Epigenedit, to explore why hyperbaric oxygen therapy may be one of the most overlooked tools in longevity science.

We talk about her journey from a small village in East Germany to becoming known as the “Queen of Needles,” how she reversed markers of biological aging, improved her VO2 max in midlife, and why oxygen, mitochondria, skin health, resilience, and reinvention are all deeply connected.

Key Topics:

• Hyperbaric oxygen therapy and its role in longevity

• Innovations in aesthetic medicine and needling techniques

• The impact of oxygen saturation on aging and skin health

• Biomarkers of aging and how hyperbaric oxygen influences them

• The use of peptides and biohacking for healthspan extension

Timestamps:

• 00:00 – Reversing Biological Age? The Power of Oxygen

• 00:30 – From East Germany to Elite Medicine

#179: 📱 How A Text Message Changed US Drug Policy

On April 18th, Bicycle Day weekend, no less, the anniversary of Albert Hofmann’s first LSD trip, US President Donald Trump sat in the Oval Office and signed an executive order to accelerate research into psychedelic drugs and expand patient access.

According to Joe Rogan, who was standing right there in the room, here’s how it happened: he texted Trump some information about ibogaine.

Trump texted back.

“Sounds great. Do you want FDA approval? Let’s do it.”

Rogan described it as “literally that quick.” CNN

Policy by text message.

Welcome to 2026.

What The Executive Order Actually Does

The executive order directs $50M from the Department of Health and Human Services to match state investments in psychedelic research.

It also calls for the FDA to give expedited consideration to certain psychedelics that meet specific criteria.

More specifically: the order directs the FDA Commissioner to provide National Priority Vouchers to psychedelic drugs that have received Breakthrough Therapy designations for treating serious mental illnesses.

The National Priority Vouchers essentially fast-track regulatory review to weeks instead of the standard year-long timeline.

It also instructs the FDA and DEA to establish a pathway for eligible patients to access investigational psychedelics, including ibogaine, under the Right to Try Act.

Trump, for his part, seemed genuinely enthusiastic. Before signing, he pointed to early research on ibogaine’s potential, then joked, “Can I have some, please?” “I’ll take it. Whatever it takes.” to which the audience laughed.

Ibogaine, derived from a shrub native to West Africa, is named explicitly twice in the executive order. It has been championed by veteran organizations and psychedelic advocates as a promising treatment for hard-to-treat conditions including opioid addiction, PTSD, depression, and traumatic brain injury.

Why ibogaine, and why now

Ibogaine has been building momentum, quietly, while the rest of the mainstream psychedelic conversation centered on psilocybin and MDMA.

Ibogaine was classified as a Schedule I substance in the United States in 1970. Due to this illegality, in recent years, US veterans have reported benefiting from ibogaine after travelling to clinics in Mexico to access it.

That grassroots pressure, combined with backing from veterans groups and former Texas Governor Rick Perry, who co-founded a group called Americans for Ibogaine and made the case for reducing federal limits on the drug on Rogan’s podcast, twice in two years, led to a law providing $50 million for ibogaine research in Texas.

Trump’s executive order appears designed in part to match and amplify exactly that kind of state-level momentum.

The clinical trials are preliminary and limited on Ibogaine due to the Schedule I classification, which makes it almost impossible to study the compound domestically in the United States.

One of the only recent studies conducted by US researchers was done by a Stanford research group who enrolled 30 veterans who then received Ibogaine in Mexico. They found that veterans treated with ibogaine showed improvements in PTSD, depression, and anxiety symptoms.

Ibogaine is known to cause irregular heart rhythms and has been linked to more than 30 deaths in the medical literature.

That is a significant safety concern that has stalled research for decades. The FDA has resisted ibogaine research partly due to concerns about heart-related risks, and most research has been conducted abroad.

What the executive order does is create the conditions to finally study it properly, in the USA.

Frederick Barrett, director of the Johns Hopkins Center for Psychedelic and Consciousness Research, says: “It’s been incredibly difficult to study ibogaine in the US because of its known cardiotoxicity. If the executive order can pave the way for doing objective, scientific research with this compound, it would help us understand whether it is truly a better psychedelic therapy than others.”

While the executive order is a symbolic act signalling unusual openness to scheduled substances as potential treatments, it doesn’t fundamentally change the evidence on safety and efficacy the FDA would need to see.

There’s also a real risk of moving too fast. And, then there’s the access question.

Even if ibogaine clears FDA approval someday, clinic owners note there will be no insurance coverage, and it will still be considered unapproved, non-covered care.

Access will initially remain a privilege of the wealthy.

The people who need it most, veterans, people with treatment-resistant depression, those without the means to fly to Mexico for treatment, will still be waiting.

Whatever you think of the currently political circumstances, and I have thoughts, the framing shift on psychedelics matters.

The stigma around Schedule I drugs is significant, and this gives political cover for Republican governors and legislatures to step into the ring and fund research programs at their universities. States that might have been fence-sitting may now feel safer moving forward.

For those of us who have spent years watching rigorous psychedelic science get dismissed, defunded, or simply ignored, the idea that ibogaine is being discussed by name in the Oval Office is genuinely surreal.

IKEA is trying inflatable furniture again.

Yes, really.

After their famous 90’s fail - where their inflatable range turned out prone to dust, delation and being destroyed by a passing vacuum cleaning.

Now they’re back, and apparently they’ve cracked it.

The new easy chair, designed with Mikael Axelsson, has a foam cover, a carbon steel frame, and it is…full of air.

But the textile cover means no squeaking, no sliding and actual back support. It looks surprisingly solid.

And honestly, I have to admit, it’s kind of cute.

#178: My Accidental Workout Stack

Nobody handed me this workout routine, I ended up building it by following what felt right to my body. And…somewhere along the way, I accidentally ticked almost every box the longevity research says matters.

I’ve been active my whole life, cheerleading and track in high school, cheerleading in college. I fell off when I no longer had a coach pushing me, then found my way back in grad school through CrossFit-style workouts and dance classes.

After that I had to figure out how to sustain it on my own, which took a while. What I learned about myself: I like being told what to do. I want to show up, do the workout, and leave without having to think too hard about it. That’s not laziness, that’s knowing yourself.

So I chased classes. OrangeTheory, hot yoga, power pilates in San Francisco and Berlin, Beat81, Barry’s Bootcamp.

As I learned more about longevity, I got more intentional about balance. The research is clear: you need strength training, cardio, and mobility work, ideally all three, consistently.

Which meant I was trekking all over Berlin or San Francisco to hit different studios for different things.

When I landed in Lisbon in the winter of 2022, I found Amplify. And I’ve been going ever since.

In the beginning of my time in Lisbon in that winter of 2022, I was living in Baixa, so getting to the Amplify studio meant a 20-minute uphill walk. I’d do a bootcamp class and walk back home. Between the walks, the workouts, and eating well, I genuinely think I was the healthiest and happiest version of myself that winter. I came back to Berlin tan and fit, having lost about 10 lbs, and tried to carry that momentum forward.

When I moved to Lisbon permanently in 2023, I signed right back up to Amplify. The bootcamp classes became my anchor - 10 minutes on the treadmill, 10 minutes strength, repeat. I did this three or four times a week, no question.

Resistance training is one of the most important things you can do for longevity. After 40, you lose 1-2% of muscle pass per year if you’re not actively fighting for it.

Muscle is protective, metabolically, structurally and for independence later in life. Bootcamp class is my prescription for that.

Then a friend told me I hadn’t even scratched the surface of Amplify if I hadn’t tried Miki’s cycling class. I went. The man has a gift.

It was the hardest class I’d ever done, the energy was through the roof, and at one point Miki was literally on the ground with his fist down, giving us a full motivational monologue about being in our bodies, becoming our best selves. You walk out of that class feeling like you can do anything. I was hooked.

Cycling at that kind of intensity is exactly what longevity literature calls for.

Your VO2 max, your body’s capacity to use oxygen, is one of the strongest predictors of all-cause mortality. The research shows that moving from “low” to “above average” VO2 max cuts your risk of dying more than quitting smoking.

For me, that means Miki’s cycling class is basically a longevity drug.

After a bad ankle injury eventually took running off the table, I went deeper into cycling and then yoga. A year or two in, Amplify opened a new location in Santos, where they have a bigger studio and added Barre classes.

Now my routine is a mix of everything: two or three bootcamps a week, one cycling class, and barre or yoga on top of that.

Flexibility and stability work isn’t just recovery, it’s core to your longevity too. The ability to balance on one leg for 10 seconds is an independent predictor of survival in your later years. Barre and yoga are my way of working on that.

I’m at Amplify four times a week. I hit 250 classes recently, and I’m still going. One thing nobody tells you about Amplify: people bring their dogs. This is, objectively, one of the best parts of my day.

Post-workout, I grab a smoothie. My order: the Boogie Matcha. Everytime. This helps me get my protein in right after a hard workout. Protein matters more than most people realize, and your muscles are most receptive to protein in that window right after training. Getting protein in after a workout is one of the easiest optimizations you can make.

Beyond Amplify, I dance. Pop dance once a week at Jazzy Saldanha, and high heels dance twice a week, which is as much work as it sounds and connects me to something completely different.

In 2017, researchers found that dance was more effective than traditional exercise at reversing brain volume loss in the hippocampus. This is because dance requires constant new learning, new choreography, new spatial awareness, and new timing.

That’s a cognitive challenge on top of a physical one. High heels specifically trains proprioception and balance in ways that flat-footed dance training doesn’t.

I also play padel once or twice a week for the social aspect. Longevity research has also identified social connection as a strong predictor of a long, healthy life - equally powerful to exercise and diet. Padel is a great way for me to get in extra movement and my social time.

My workout framework, if you want to steal it:

- Amplify is where I build the foundation: strength, cardio, mobility, all under one roof

- Dance is for my brain: neuroplasticity, body awareness, learning something new

- Paddle is for my social health: connection, fun, lateral movement

I designed it by following what I enjoyed. The fact that it maps almost perfectly onto what the research recommends is either a coincidence or proof that your body knows something.

Either way: it’s a life I love.

📚 Book of the Week

The Hallmarked Man by Robert Galbraith

Rating: ★★☆☆☆

You may have noticed there wasn’t a book of the week the last two weeks. One reason was…I’m still reading this long damn book. Another reason was #176 was an emotional essay that needed to stand alone.

While I’m still not done with this book, I’m ready to rate it, or give it up.

It’s an 18 hour read according to my kindle, and I’ve dragged myself through over 50% and I can say that it’s a frustrating amount of “Cormoran loves Robin, and Robin loves Cormoran” but neither of them have the confidence to say so and are therefore living unfulfilled lives.

The main plot line moves along at a glacial place - Cormoran and Robin are investigating a mysterious body found inside of a silver shop’s vault. Meanwhile, balancing a few other clients and Cormoran has to face a public scandal.

I’ve read all seven books in this series so I feel I owe it to myself to finish this one too, but it’s truly the most boring one thus far, and it only gets 2 stars.

But although the winning robot from Chinese smartphone manufacturer, Honor, is faster than the humans…another robot started the race by falling on its face.

#177: 🤖 I’ve Been Using Claude Code for 25 Days. Here’s What I Built.

I attended a 4-hour AI intro class and that was all I needed to enter the future.

Now I want to tell you what happened over the next 25 days.

Using Claude Code has been a gift to my ADHD. For the first time in my life, I feel like I can put all the open tabs in my brain into ONETAB.

I can organize all of my work, visualize it in a way that makes sense, and actually execute on it instead of cycling through it at 2am.

If you have ADHD, get ready to supercharge your superpower.

While other AIs have been great to organize my thoughts… Claude Code takes it further. It lets you execute on all those ideas you’ve been hoarding.

I will admit that it is a fine balance between AI enhancing my ADHD superpower versus making my ADHD worse…but my thoughts on that are for another newsletter.

In 25 days, I launched:

• Two cash-generating products (the Women’s Longevity Starter Kit and my proprietary Pitch Deck Analyzer

• Rebuilt three websites

• Built an interactive daily briefing dashboard that pulls my entire business pipeline in one command

• Created tools for better LinkedIn outreach

• Built tools for SEO optimization across the entire Nina’s Notes archive

• Fed Claude my entire knowledgebase and now get ideas for Substack Notes & YouTube short scripts in my daily briefing dashboard

• Built the full Longevity Day event website - with the program and speaker pages.

11 projects. 60 individual files and tools.

And the best part…I am not a developer.

I started on March 20th by taking Nick Sarafa’s LightSchool AI intro class. It was 4 hours long and that was enough to give me the tools to run wild.

Want to join his class?

He offers it in person here in Lisbon and also offers online classes - grab a spot here.

The product I tried to build a year ago and why it failed.

About a year ago I had an idea, take all the pitch deck feedback I’ve given to founders over the years, distill it into core principles and turn it into a product.

I did the first part. I fed transcripts into ChatGPT, extracted the principles, and built a markdown file.

I even tried to make a customGPT, the concept was solid.

But the output was inconsistent. It hallucinated.

The feedback didn’t feel reliable enough to charge money for.

The interface was awkward and I had no idea how to attach payment to it. So it just…sat there.

So when a founder sent me their deck, I would pop it into ChatGPT alongside my Pitch Deck Principles markdown file and ask for an analysis to test it.

Fast forward a year, and 25 days after opening terminal for the first time in ages. I rebuilt it.

I built the landing page, payment processing, PDF upload, AI analysis and PDF download - all of it…in about six hours (try it here: Pitch Deck Analyzer).

The idea didn’t change, but the infrastructure I could use to build it did.

What did I learn over the last 25 days?

Lesson 1: Get over your terminal anxiety.

Claude Code in the terminal is 100x better than Claude Chat or Claude Cowork.

Those interfaces exist for people who want a nice UX and who are scared of the terminal. I was one of those people, and thank god I’m not anymore.

I currently have five terminal windows open at once, different projects running in parallel, and I genuinely love it.

There’s something about the terminal that strips away the pretty and just lets you build.

(However…you can even make your terminal prettier by simply telling Claude - “make my terminal prettier”. It’s ridiculous.)

With Claude Code, I am building real, functional python scripts that live on my computer and run without Claude afterward.

With those scripts, you’re not just getting text replies from Claude, you are creating infrastructure. Personalized tools that work for your workflows.

No biggie guys, I’m just a junior developer over here now.

And it’s a good feeling.

Lesson 2: Connect Everything.

I know, I know…what about data privacy. (AHHH DER DATENSHUTZ!!!)

Here’s my take and maybe it’s the American in me, but these big companies already know everything about us anyway. Stop letting that anxiety keep you disorganized.

I connected my Gmail, Google Calendar, and my CRM.

My morning briefing now pulls live data automatically.

I ask it to look at my last 7 days of emails and look at the week ahead on my calendar. I need this tool to tell me what’s urgent and tell me what needs nudging.

I made it interactive so I can check things off when they are done and Claude automatically updates my CRM and to do list. (exhale, sigh of relief)

I used to hire people to do this coordination work and be the human layer between all my different systems. I needed an assistant to make sure I didn’t drop the ball on something.

Now it’s one click and my briefing reminds me of everything.

This is hours returned to me, every week, FOREVER.

Lesson 3: Claude Code remembers. Claude Chat doesn’t.

This is why I love Claude Code in the terminal.

When you use Claude in Chat or Cowork, it only remembers what’s in that conversation. It has a vague sense of you, but the moment that chat ends and you start a new one, that context is gone. Every new conversation starts cold.

You can amplify this by using projects and loading files in there, but it has memory storage limitations. For example, I tried to load all of my Nina’s Notes markdown files into a Project in Claude last year, and I ran out of memory in the project by #99. And due to the gap of nearly 50+ Nina’s Notes missing, I didn’t use that project as much as I could have.

In the terminal, when I tell Claude to remember something, it writes notes about me into plain text files that live on my computer. My Claude knows my CRM structure, my product strategy, my tone, my goals, my brand guidelines - all of it.

Think of these like notes a good assistant would keep about you between meetings.

Every new terminal session reads those files. So Claude picks up exactly where we left off, every single time.

That’s the biggest reason I live in the terminal now. It’s not just the speed or power, it’s the continuity.

It’s the difference between a young forgetful intern and a brilliant assistant who actually knows you.

And because it’s just files on your computer, you can read them, edit them, and add them yourself.

You are in control of the memories.

Lesson 4: Find the people building with AI.

Last Friday, I hosted a three hour vibe coding session at my flat.

Everyone was working on something completely different.

One friend was building an app to clean up duplicated photos off her phone.

Another person, an actual developer, was trying to load a massive biological dataset into Claude. He hadn’t used Claude Code yet…and he’s a developer (gasp!!). Getting him set up, watching him realize what’s possible with his own dataset, that was super cool.

I launched a product in three hours! While we were talking and laughing and sharing our struggles getting the AI to work out loud.

I want to do that every Friday.

The people using AI to actually write and run code are thinking differently. Not better necessarily, but they are thinking differently.

They are not using AI just to polish emails. They are using AI to build systems, automate the boring parts of their workflows and create things that didn’t exist yesterday.

We are still a small fraction of AI users.

That gap is closing fast.

You don’t need to understand every line of code, but you do need to start thinking like someone who builds. You need to find the people who are building and get in the room with them.

Do you want to build with me?

I’m doing vibe coding Fridays in Lisbon and I’m thinking about what this could look like online.

I’m not ahead of you by much, just by 25 days. And I want to bring you along with me.

I’ve put together a starter kit and am running live vibe coding sessions online.

Count me in

#176: 🤕📉 What Having Two Chronically Ill Parents Taught Me About Longevity

First off, my parents had me when they were “older.” I put this in quotes because what was “old” to their generation is the age that most of my friends are even considering having kids today.

My mom was 36 and my dad was 40 when they had me.

Because of this, I am experiencing my parents aging earlier respectively than most of my friends, who have parents in their 60s right now, while mine are 74 and 78.

While they are aging, and with aging comes changes, that’s not when the chronic illnesses began.

I grew up in a smoking household. Both of my parents smoked indoors, windows closed. Smoked in the car, window cracked. We sat in the smoking section of restaurants (back when they used to have that). As I grew up, we would socialize at the bar in the local casino, where you can smoke openly.

Dad smoked cigars. Mom smoked cigarettes.

Mom started smoking at waking, and smoked until bedtime. About 2 packs a day.

Their rule - “We don’t smoke upstairs.”

Our two-story house has very high ceilings but the living room doesn’t have a floor above it…and well…smoke rises.

My bedroom and childhood playroom, which was converted to my office in my teens, are on the second floor. The office doesn’t have a door.

Secondhand smoke was part of my life - no choice in the matter.

I didn’t realize it had an effect on me.

I really thought that was just how life goes.

The times I would notice the effects of secondhand smoke was always when the track season started. The first week of track season we called “hell week” - you THOUGHT you were in shape. Nope - hell week taught you that was a lie. We were out on the track, doing hard workouts, Rounds of sprints with sometimes positive amounts of rest (meaning more rest than the time spent running, ex. 45 sec sprint, 90 sec rest) or sometimes negative rest (less rest than the time spent running, ex. 30 sec rest after a 45 sec sprint).

Always during hell week, I would experience what I can only explain as an asthma attack.

But I would feel my chest tighten to a point where I was wheezing and gasping for air. It would feel scary, but I could calm down after a few minutes.

My coach would ask if I had an inhaler, but I would say no. I was never diagnosed officially.

I thought this was just part of training.

If I worked myself 120%, that’s just what lungs do, they start to panic.

I’d see other teammates very out of breath, but….they didn’t have this.

It never stopped me from being an athlete, and usually after hell week and the first weeks of training, I wouldn’t have any more asthma attacks. It would really only happen if we did something new in training, like a hills day with lots of sprints, or something that really pushed me.

I just thought that asthma attacks came because I was out of shape.

I also never realized how the smoke was affecting my mom.

She had a cough - a smoker’s cough. Deep. Thick. Musousy. Painful to hear.

When she laughed really deeply, it would cause her to cough.

This would happen to me too - I thought it was a character trait.

As the years went on, the coughing became more and more, and that was just…how she was.

Then…I moved out of my parents house to go to college.

I don’t remember exactly how many years it took, but I started to regain my sense of smell.

When I would come home from school to visit, I would notice how smokey the house felt.

I would open windows to get fresh air - only to be met with objections that it was “too cold” and to close the windows.

I would do laundry at my parent’s house, but when I got back to college, I’d open my bag and all my clothes would smell like cigarette smoke, and I had to wash them all again.

I didn’t train as much in college as I did in high school, but I really noticed a difference in myself when I started training again in grad school, 4 years after moving out of my parent’s house.

I signed up for a body-weight CrossFit-type workout with a trainer.

The workouts were HARD. We would do sprints with negative rest, as many reps as possible (AMRAP) and other exercises to get your body to fatigue.

….And I wouldn’t have an asthma attack.

I thought then - I’m just not training hard enough. I can push myself harder.

The asthma attack was my internal signal that I’d reached my limit.

And they…stopped.

I had read that your lungs can heal if you quit smoking. You regain your sense of smell, and you can start to breathe better.

And it was happening to me.

I’m not sure if it took four full years, but it took time and the repair was there the whole time.

My mom quit smoking about 5 years ago, after smoking for most of her life. She quit after she had a really big scare - one that landed her in the ER with oxygen to breathe. And she said - No, this is not how I go. She quit cold turkey.

Since then, she’s regained her sense of smell, and now Dad is forced to smoke his cigars outside.

She has an official diagnosis of Chronic Obstructive Pulmonary Disorder (COPD), which she’s likely had for decades.

And, she uses an oxygen machine to get her O₂ blood levels to something where she can, but she is constantly out of breath. She is constantly fighting to breathe. Her cough persists. It’s loud, it’s hacking. It must be so, so painful.

To add another layer, my mom has scoliosis. This is a curvature of the spine. Her spine is in the shape of an S, which causes her ribs to twist around and causes her a lot of pain. She also has severe disc degeneration.

I remember as a kid she would wear a hard plastic back brace to help correct for the S curve, but I don’t think it helped tremendously and was eventually abandoned. She tried everything from specialized chairs, pillows, back massages, topical medication, physical therapy and cortisone injections.

Then and now, she has always been in a lot of pain, which she managed and numbed with pain killers. Also during this time she was depressed and anxious.

Her coughing, the scoliosis, the depression…all of it is a lot to carry, and she turned inside of herself to cope.

Growing up, I remember that she did not exercise because it would hurt her back. She would spend a lot of time indoors, working, writing, reading. Very solo-focused activities and hobbies.

Dad, on the other hand, was diagnosed with diabetes after spending perhaps a decade or so overweight (~200lbs).

After the diagnosis, and our move from SF to Las Vegas, he set upon a very diligent exercise routine.

Everyday - 3 mile walk, carrying weights. He lost the excess weight, even got down to ~145lbs at his slimmest.

But the diabetes stayed.

At first, the diabetes was manageable with metformin and the other diabetes pills. Unfortunately, diabetes is a progressive disease.

People think we’ve got it figured out. We have insulin - diabetes is fixed! No no no, I truly disagree.

Diabetes is an incredibly debilitating disease. High blood sugar causes nerve damage (neuropathy), retinopathy (which can lead to blindness), chronic wounds, and even kidney disease. The worst cases lead to amputated limbs.

I can’t remember exactly when my dad was diagnosed with diabetes, let’s say I was about 8 years old. I’m now 38.

Over the last three decades, I’ve seen this disease slow my dad down.

Managing blood sugar with pills turned into requiring insulin injections.

He’d have to check his blood sugar several times throughout the day with the old finger prick reader.

He’d have episodes where his blood sugar was 500, and he’d be screaming in pain from the neuropathy in his feet.

Now, he’s lost the sensitivity of touch in the tips of his fingers - making it hard to text with touchscreens and he’s losing his vision due to retinopathy.

He’s lost consciousness several times from taking too much insulin and depleting his blood-sugar to critical levels which required paramedic intervention.

When your brain doesn’t have enough sugar to use as energy - it shuts down.

He reached this level at least 6 times.

He has fallen down on his walks due to low blood sugar and had head injuries. On Christmas day a few years back, he fell while going for his walk, landing him in the ambulance and ER for a fractured orbital lobe and stitches.

Sometimes, it’s not a true loss of consciousness. It’s more like a sitting zombie. Eyes open. But no response or movement if you try to communicate. And unfortunately, you can’t get him to eat or drink at this stage to move the blood sugar up. Injecting him with glucose from a syringe is the only option.

And then, like a miracle - he’s back within seconds. And….now on a sugar high.

Nowadays, he is showing signs of cognitive decline and memory loss. It could be from these low blood sugar moments that did lasting damage to the brain.

These low blood sugar events are preventable. My dad was taking too much insulin. He was listening to his doctor’s recommendation.

I spent a month with my dad traveling through Australia in January, and I fixed these blood sugar crashes by adjusting his diet and insulin accordingly. Read more about that adventure here.

Dad’s also had some major surgeries - he went for a quadruple bypass in January 2023. And recovered incredibly well because it was a proactive surgery - not after a heart attack.

I have to give my dad credit here. His 3 mile walks every day for nearly 40 years, with weights, has made the man incredibly fit, strong and his recoveries are outstanding. Without that muscle and exercise, I can’t imagine what his recovery would look like.

He also shattered his femur from a fall in 2015. He had the surgery to fix the bone with rods and screws and was walking within 2 months because he had strong muscle around the bone to hold it in place.

Also, even though he still smokes cigars daily - maybe just 1 to 3 a day. He’s never developed COPD like my mom. I think the daily walks work his lungs and allow him to fight that long-term exposure to smoke.

Watching my parents, as a kid, as a teen, and even now led me to make very concrete decisions about my health.

I decided very young to never smoke. I think I’ve tried 1 cigarette, and 1 puff of a cigar in my entire life.

In high school, some of my friends were smoking marijuana for the first time. I also passed on that. I didn’t want to smoke anything.

Daily fitness became a non-negotiable. In middle school and high school - always training with my track team, or cheerleading team, dance, and gymnastics.

College was more difficult because for the first time I didn’t have a coach. I fell out of training. I’d try to go to the gym, but I would just run on a treadmill. I was intimidated by the weights, and the gym was arranged in a way where the weight floor was usually only the men, and the women on the second floor with the ellipticals, treadmills and bikes.

I got a bit out of shape over those 4 years. I lost my muscle.

I remember really noticing it once when I wanted to get out of the deep end of a pool. To get out, you basically do a pull up and then an extension to lift yourself to your hips to be able to sit on the ledge…and I couldn’t do it. My arms had gotten so weak that I really struggled to press up my own body weight.

When I got to grad school, I arrived in Tucson four weeks before the term started. I didn’t have many friends then, and Groupon was alive and well. I bought every gym pass I could at a discount and I got back into training 4 days a week, with a better diet, and I regained my strength.

Since age 21, I’ve been exercising about 5 days a week - a combination of HIIT class, running, yoga, pilates, and dance. I walk everywhere as much as I can.

In grad school I studied epigenetics, now a household term, but back in 2010-2015 it was just emerging as linked to longevity.

I never directly thought I’d study epigenetics because of my parent’s health but, looking back now, it connects. We can change our epigenetics when we change our environment, or behavior, or habits.

While I never tested it, I imagine the epigenome of my lungs changed significantly over the years since I was exposed to secondhand smoke.

Watching my parent’s health through my whole life led me to the decision that I do not want my health to decline the way theirs has and is continuing to do.

My parents didn’t have this information. They didn’t have a framework. They had stress, habits, circumstances, and no one telling them that the daily choices they were making would compound, decade over decade, into the bodies they have now.

I don’t blame them. I love them deeply. And growing up with them has been one of the most formative educations of my life.

What I know now, that they didn’t know then:

Chronic disease is largely preventable. And the prevention is not complicated.

Move your body. Every day. Even a walk counts, as my dad has proven for 40 years.

Don’t smoke. Don’t numb. Don’t sit still.

Protect your lungs, your blood sugar, your spine, your mind.

The body keeps score. It keeps a very, very long score.

All of these life experiences led me to study longevity for a living, where I interview scientists, read the papers, and write the notes. But the reason I care so deeply about it isn’t just intellectual curiosity.

It’s personal.

It started in a smoky living room in Las Vegas, watching my mom cough and my dad check his blood sugar.

And it never stopped.
