With Index you'll receive: Biological age: the age your body is expected to perform or function. Cumulative rate of aging: the pace at which your body has been aging, also called your pace of aging. System age scores: the biological age of nine different systems, including brain, heart, metabolic, and immune, for deeper insights into how you’ve been aging. Science-backed recommendations: evidence-based lifestyle recommendations you can use to adopt healthier habits.
