Are you a rapid ager? Biological age is a better health indicator than the number of years you’ve lived, but it’s tricky to measure

Aging is a major risk factor for many chronic diseases. Figuring out what influences longevity and how to identify rapid agers could lead to healthier and longer lives for more people.

Epigenetic and social factors both predict aging and health – but new research suggests one might be stronger

People don’t all age at the same rate. Untangling the factors that influence health and disease – such as epigenetics, demographics and behavior – could lead to better care for those who need it most.
