Age Faster or Slower? The Surprising Role of Mental Health and Self-Control
In a recent "Longevity by Design" episode, Dr. Terrie Moffitt of Duke University explains how early‑life mental health and self‑control shape the biological pace of aging, drawing on the 50‑year‑long Dunedin Study. The research shows that mental disorders in youth accelerate aging biomarkers, while strong self‑control correlates with better health, relationships, and financial stability later in life. Moffitt also details a new epigenetic blood test that quantifies an individual’s aging rate, making the metric usable beyond the original cohort. The conversation argues that treating mental health early could become a cornerstone of longevity strategies.
