The Human Awareness of Mortality
Human beings possess a unique awareness of mortality that significantly shapes their culture and worldview. Unlike other species, which may recognize death, humans understand that their lives have an expiration date, influencing social constructs and individual behaviors. This profound understanding drives existential reflections on life, aging, and the quest for immortality. The realization that aging is intrinsically linked to mortality underlines the urgency for scientific exploration into the mechanisms of aging and the possibilities for extending healthy lifespans.
