Wealth predicts up to 20 years of healthy aging, study finds

New research published in *PLOS Medicine* found that people with less wealth have up to two decades less healthy physical function in older age compared to wealthier individuals. The analysis, led by Dr. Paola Zaninotto, used longitudinal data from England and Canada, suggesting socioeconomic status isn't just about current health, but how long your body keeps working optimally.
