Healthspan and lifespan are different metrics. Below: what the published research describes about the markers, mechanisms, and interventions linked to longer, healthier life.
A practical guide to the main ways to estimate biological age — epigenetic clocks, blood-biomarker scores, grip strength, VO2 max and telomere tests — and how reliable each is.
