Dr. Sinclair says he regularly studies his fingernails to estimate how quickly he is aging. For most people, nails are rarely the first place they look when assessing health. We usually focus more on diet, heart, lungs, and general wellbeing than on fingernail changes. However, he explains that nails can reflect how efficiently the body produces new healthy cells. Faster cell regeneration is associated with stronger protection against age-related decline.
