Aging is a major risk factor for disease.
People age at different rates. We need to measure people’s biological age to get an accurate picture of their health status and risk for age-related illness.
Biological versus chronological age
Biological age varies among people of the same chronological age. Biological age is a better predictor for mortality and morbidity than the number of years you have lived.
