In this episode of The Dan Buettner Podcast, world-renowned demographer Dr. Jay Olshansky joins Dan to debunk the viral myths surrounding human longevity. While social media often promises a future where we live to 150, Dr. Olshansky reveals the hard biological truths and explains why we are hitting a "glass ceiling" of life expectancy. He breaks down the concept of "manufactured time," the reality of the "red zone" of aging, and why he considers much of the anti-aging supplement industry to be modern-day quackery. Instead of chasing expensive and unproven "cures," Dr. Olshansky shares evidence-based habits—from high-grade fuel to social connectivity—that can actually help you maximize the genetic potential you were born with.
