The Importance of Biological Age in Measuring Health

Biological age, which measures physical and functional ability, is a more accurate indicator of healthspan than chronological age. Genetics, environment, lifestyle, and stress all contribute to biological aging. Social connectedness, exercise, and diet are strong influencers of biological age. Scientists are interested in identifying a molecule that is sensitive and specific enough to serve as a unique fingerprint for biological age. Promising molecular markers include epigenetic clocks, senescent cells, and unique metabolites. Delaying biological age may be one way to live healthier, fuller lives.
