Loneliness can cost you up to 20 years of healthy life. More than poor sleep. More than any supplement. And until now, there was no way to measure it.
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.

ABOUT DR. AXEL SCHUMACHER: Longevity scientist and epigenetics researcher with over 25 years of experience, believes the most powerful biomarker for how long you live isn’t in your blood it’s in your relationships. After decades at the forefront of genomics and biomarker discovery, he now focuses on quantifying human connection, developing the Social Connectivity Value (SCV), a first-of-its-kind framework to measure your social network as a health metric and longevity tool.
