Peak Function Span

Meaning

Peak Function Span is a sophisticated conceptual metric in longevity medicine that precisely quantifies the duration of an individual’s life during which they maintain optimal, high-level physical, cognitive, and hormonal performance, clearly distinguishing it from mere biological lifespan. Extending the peak function span is the central, proactive goal of modern health and wellness interventions, focusing intently on maximizing the quality, vitality, and functional independence of later years. It represents the duration of maximal biological reserve and homeostatic capacity.
