What is the Origin of Vitality Span?

This term is a conceptual refinement of the term lifespan, focusing on the qualitative experience of life rather than merely its chronological duration. Vitality is derived from the Latin vita, meaning life, emphasizing the energetic and functional quality of the years lived. The clinical goal is to compress the period of morbidity at the end of life.

What is the Mechanism of Vitality Span?

The underlying mechanism for extending the Vitality Span involves preserving the functional reserve of key physiological systems and maintaining cellular resilience. This includes optimizing mitochondrial health for sustained energy, ensuring hormonal balance for mood and metabolism, and promoting neuroplasticity for cognitive maintenance. By supporting these foundational biological processes, the body and mind retain their functional capacity for a longer duration.

Vitality Span

Meaning

Vitality Span is a clinical and subjective measure of the period during which an individual experiences a high quality of life, characterized by robust energy, excellent cognitive function, and freedom from chronic, debilitating disease. This metric is a more human-centric counterpart to Healthspan, emphasizing the subjective experience of vigor and mental clarity alongside objective health markers. Maximizing the Vitality Span is the core mission of modern longevity medicine.
