Harvard-trained longevity expert reveals surprising link between nail growth and aging
Harvard-trained longevity doctor David Sinclair suggests nail growth can be a surprising indicator of biological age. A 1979 study found nail growth slows by approximately 0.5% annually after age 25, declining by 50% over a lifespan, reflecting reduced cellular regeneration. This, along with other factors, offers insights into how well the body is aging.
