Performance Longevity Metrics

Meaning

A set of quantifiable physiological and functional measurements used to track both the duration of life and the quality of healthspan, specifically focusing on the maintenance of high-level physical and cognitive performance into advanced age. These metrics integrate traditional longevity biomarkers, such as telomere length, with functional assessments of strength, endurance, reaction time, and executive function. They provide a holistic view of aging that values functional capacity as much as disease absence.
