In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dr. Terrie Moffitt, University Professor at Duke University. They explore the deep link between mental health, self-control, and the pace of biological aging, showing how early-life mental disorders can shape health decades later.

Terrie describes her work with the decades-long Dunedin study, which tracks health from birth through midlife. She explains how people age at different rates, even when born in the same year and place, and how the “pace of aging” can be measured using biomarkers. Terrie shares that fast agers show early signs of physical and cognitive decline, while those with strong self-control tend to experience better health, stronger relationships, and greater financial stability as they grow older.

The discussion reveals that treating mental health issues early in life could prevent chronic diseases and slow aging itself. Terrie makes a strong case for taking mental health seriously, both as prevention and as a path to a longer, healthier life.
