333 ‒ Longevity roundtable—the science of aging, geroprotective molecules, & lifestyle interventions

Video Description

In this special episode of The Drive, Peter introduces a brand-new roundtable format. Joined by three renowned experts in longevity science—Steven Austad, Richard Miller, and Matt Kaeberlein—the group explores the rapidly evolving field of geroscience. Together, they dive deep into topics like the relationship between healthspan and lifespan, evaluating interventions like rapamycin and senolytics, the role of epigenetic changes in aging, and whether GLP-1 receptor agonists hold geroprotective potential. They also tackle major challenges in funding and public acceptance of longevity research including how geroprotective interventions might be tested in humans. Packed with nuanced debate, humor, and groundbreaking insights, this episode is a must-listen for anyone fascinated by the science of aging.
