Can something really predict how long you'll live—better than your genes?
This episode breaks down one of the most overlooked yet powerful predictors of lifespan: social connection. Based on landmark studies like the Harvard Study of Adult Development and meta-analyses spanning over 300,000 participants, we explore how loneliness, emotional isolation, and the quality of your relationships directly influence your risk of chronic disease, cognitive decline, and early death.
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:

The 85+ year Harvard Study on Adult Development
Research on oxytocin, inflammation, and the vagus nerve in connection to relationships
