Your biological age reflects how your lifestyle choices are aging your body at a cellular level. This questionnaire assesses seven key factors including sleep, exercise, diet, stress, and social connection.
Biological age refers to how old your body appears physiologically, based on markers like inflammation, telomere length, metabolic health, and organ function — rather than years lived.
Research consistently shows lifestyle factors can shift biological age by 5–10 years in either direction. Sleep, exercise, diet, smoking status, stress, and social connection are among the most powerful modulators.
For a clinical assessment, epigenetic "clock" tests (such as Horvath's clock) can measure biological age from a blood sample.
