Functional Prime Duration

Meaning

Functional Prime Duration is a conceptual metric representing the period within an individual’s lifespan characterized by the peak expression of their physiological resilience, cognitive capacity, and overall physical performance, coupled with optimal hormonal balance. It defines the maximum span of years lived in a state of high function, independence, and minimal chronic disease burden. The clinical goal of longevity medicine is to actively intervene to extend this duration as far into chronological age as possible. It signifies a state where the body’s repair mechanisms operate with maximum efficiency.
