Episode Description from the Publisher

David Stewart has spent much of his life looking closely at people.As a photographer, he worked around the world, shot his first Vogue ad in his twenties, and worked in New York during the Andy Warhol era. But as David got older, he began noticing something strange: while youth was marketed through aspiration, possibility and beauty, aging was increasingly framed through fear, decline and limitation.He decided to challenge that story.Today, David is the founder of SuperAge and AGEIST, building a new model around longevity that goes far beyond biomarkers or simply trying to extend lifespan.In this conversation, we explore what it actually means to stay fully alive as we age, why optimism may be essential to pursuing wellness, how social connection fits into longevity, the danger of turning health into an endless optimization project, and why David believes we need to move from consuming information to taking action.We also explore the creation of the Super Age Games, his personal practices for managing stress and mental fitness, and the simple morning ritual he uses to deliberately counter the negativity our minds naturally absorb.This is a conversation about making the life you have worth extending.EXCITING STUFF!My second book now available for pre-order!
