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. About Dr. Barzilai:  Dr. David Barzilai is a physician and the CEO of Healthspan Coaching LLC.
