Healthspan and lifespan are different metrics. Below: what the published research describes about the markers, mechanisms, and interventions linked to longer, healthier life.
Longevity research distinguishes lifespan (total years lived) from healthspan (years lived in good health). This page describes the definitions, measurement, and current state of the field.
