The Longevity Secret No One Talks About | ft. Shawn Stevenson

What if the most powerful predictor of your lifespan has nothing to do with your genetics, diet, workouts, or supplements? In this groundbreaking episode, neuroscientist Louisa Nicola sits down with bestselling author Shawn Stevenson to reveal the real missing piece in the longevity equation. Drawing from a massive 148-study meta-analysis of 300,000+ people and Harvard’s 80-year longitudinal study, Shawn explains why the quality of your social relationships is the strongest determinant of how long you’ll live — outperforming exercise, nutrition, and even quitting smoking.
