Summary

In this episode, we dive deep into the science of aging with longevity expert Dr. David Barzilai. You’ve probably seen people online claiming to have reversed their biological age—but is any of that actually possible? We unpack the truth behind biological age tests, anti-aging supplements, and the wildest longevity trends (yes, even blood transfusions from your kids). Dr. Barzilai explains what really works—spoiler: it's not $2 million worth of pills—and shares simple, science-backed ways to live healthier for longer. If you want to cut through the hype and get real about living better, this episode is a must-listen.

He is a founding faculty member and Trustee at the Geneva College of Longevity Science, and serves as a lecturer at Harvard Medical School. Board-certified in lifestyle medicine, Dr. Barzilai holds both an MD and a PhD in health services research.
