What is Health Age?
Health Age (Biological Age) measures how your body functions compared to your calendar age. Based on research from 'RealAge' (Dr. Michael Roizen), 'The Blue Zones' (Dan Buettner), and 'Younger Next Year' (Crowley & Lodge). Lifestyle choices — especially exercise, diet, sleep, and social connection — can make your body biologically younger or older than your chronological age.
