Can something really predict how long you'll live—better than your genes? In this eye-opening conversation, I sit down with best-selling author and researcher Shawn Stevenson to reveal the real missing piece in the longevity puzzle — one that researchers say outranks exercise, diet, and even quitting smoking.

Drawing from a massive meta-analysis of 300,000+ people, plus insights from Harvard’s 80-year longitudinal study, Shawn explains why the quality of your relationships is the #1 predictor of how long you’ll live — and why “warm social bonds” literally shape your biology, behaviors, and health outcomes. Whether you're optimizing for longevity, brain health, or emotional well-being, this may be the most important health insight you're not paying attention to. What you’ll learn: How loneliness compares to smoking and obesity in terms of health risk The neurological and hormonal effects of deep connection What the longest-lived people on earth have in common socially The difference between quantity and quality of relationships Science-backed strategies to strengthen your social fitness Referenced studies include: Holt-Lunstad et al., 2010 meta-analysis on social isolation and mortality risk The 85+ year Harvard Study on Adult Development Research on oxytocin, inflammation, and the vagus nerve in connection to relationships Follow Shawn: instagram.com/shawnmodel/ *** I’m Louisa Nicola — clinical neurophysiologist — Alzheimer’s prevention specialist — founder of Neuro Athletics.
