Summary
🧠Episode Overview What if “biological age” as a single number is the wrong way to think about aging?In this episode of The ReProgram, Dr. George Murphy sits down with Dr. Rich Miller at the Gordon Research Conference Systems Aging Meeting in Maine.Dr. Miller is a Professor of Pathology at the University of Michigan and one of the leaders of the Interventions Testing Program, the gold standard for testing longevity interventions in genetically diverse mice.This conversation challenges some of the biggest assumptions in longevity science: biomarkers of aging, cellular senescence, the search for one cause of aging, and the idea that mouse lifespan results automatically translate into human recommendations.The central message:Aging is not one pathway, one biomarker, or one number.The real question is not simply what causes aging.The real question is what can postpone many forms of age-related decline at the same time. 🔑 Keywords Richard Miller, Interventions Testing Program, ITP, aging biology, longevity science, geroscience, biological age, biomarkers of aging, aging-rate indicators, anti-aging drugs, geroprotectors, rapamycin, acarbose, ergothioneine 🧠Takeaways • Aging should not be reduced to one cause, one pathway, one biomarker, or one biological age number. • Rich Miller argues that the key question is not what causes aging, but what postpones many forms of age-related damage at once. • Lifespan is useful because it is definitive, but a true anti-aging drug should also delay multiple forms of functional decline. • Most proposed longevity interventions fail when tested rigorously. • Biomarkers of aging and aging-rate indicators are not the same thing. • A biomarker may change with age. An aging-rate indicator should tell us whether aging is moving faster or slower.…
