What is the Origin of Life Longevity?

A combination of "Life" and "Longevity" (from the Latin longus "long" and aevum "age"), representing the core objective of gerontology and anti-aging medicine. The modern clinical focus is intensely centered on maximizing the quality and functional capacity of the extended years of life.

What is the Mechanism of Life Longevity?

Research and clinical practice focus on strategically modulating fundamental aging pathways, including cellular senescence, nutrient sensing pathways (like mTOR and sirtuins), and the accumulation of cellular damage. Hormonal balance is recognized as a critical determinant, as the decline of key hormones like DHEA, testosterone, and growth hormone with age directly contributes to sarcopenia and metabolic dysfunction. Strategic interventions seek to maintain youthful cellular and systemic function.

Life Longevity ∞ Area

Life Longevity

Meaning

The clinical and biological pursuit of extending the total duration of an individual’s life, with a specific and paramount focus on extending the health span—the years lived in robust health and high functional capacity. It is a scientific discipline concerned with identifying and modulating the biological mechanisms of aging and implementing interventions to slow the overall aging process. This goal is distinct from merely prolonging existence while managing chronic, debilitating illness.
