Biological Age

An estimate of how old a person's body is physiologically, based on biomarkers rather than date of birth.

Biological age reflects the functional state of your organs, tissues and systems, independent of your chronological age. Two people born on the same day can have very different biological ages. It is estimated from blood markers (PhenoAge, Klemera-Doubal), from epigenetic clocks (Horvath, GrimAge), or from a deficit count like a frailty index. PaceSovereign uses PhenoAge for the blood route and the UK Biobank frailty index for the questionnaire route, and reports them separately rather than averaging them, because they are not measured on the same scale. Biological age predicts mortality and functional capacity better than chronological age does.
