A Two-Tier Systems Medicine Model for Human Longevity: Restorative and Regenerative Pathways to the 120-Year Lifespan Potential
2025-12-12
Abstract excerpt
Modern geroscience and demographic data suggest that humans possess a biological lifespan potential of approximately 120 years, supported by evolutionary biology, longevity demographics, and cellular aging models. Yet global life expectancy in developed nations remains only 78–80 years—roughly a 20–30% shortfall. This gap is driven not by “inevitable aging” but by preventable chronic diseases rooted in metabolic,...
