Measuring Age and Aging

Measuring Age and Aging

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.
