TED-Ed: At what moment are you dead? - Randall Hayes

The video explores humanity's fascination with death and resurrection, examining ancient beliefs like vitalism and their decline. It explains life as a series of biological processes, highlighting the role of cells and energy. Medical interventions can delay but not reverse death, though future technologies like cryonics may change this. Life is seen as a complex organization, with death as increasing entropy, and the boundary between life and death may shift with advancements.
