Natural Limit to Human Lifespan

Researchers are investigating cell manipulations, transfusions of young blood, and chemical compounds that can mimic low-calorie diets to understand the biological underpinnings of aging. The oldest verified person lived to be 122, sparking discussions about the potential natural limit to human lifespan. Evolutionary biology suggests that larger species tend to live longer to maximize reproductive potential. Some species seem exempt from this rule, hinting at the possibility of circumventing natural limits to aging.
