What Houses, Garbage, and Trucks Teach Us About Aging with Dr. Uri Alon
In a recent episode of Longevity by Design, Dr. Uri Alon presents a systems‑biology model that likens the body to a village where houses generate garbage, trucks clean it up, and a threshold determines collapse. The framework links the balance of cellular damage and cleanup capacity to mortality, disease onset, and steady functional decline. Alon also revisits lifespan heritability, arguing that after correcting for early non‑aging deaths, genetics accounts for roughly 50 % of longevity, with the remainder driven by environment and stochastic biological noise. The discussion highlights which interventions—exercise, robust immune clearance, and targeted therapeutics—truly shift the model’s parameters.
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...
Why Most Longevity Advice Gets Weight and Exercise Wrong
In a recent episode of Longevity by Design, Dr. Gil Blander interviews Dr. David Allison, director of the USDA Children’s Nutrition Research Center, to dissect common misconceptions in weight, exercise, and nutrition science. Allison emphasizes that reproducibility and transparent methodology...
