Indefinite lifespan is a term used in the life extension movement to refer to the longevity of humans, and other lifeforms, under conditions in which aging can be effectively and completely prevented and treated. Such individuals would still be susceptible to accidental or intentional death by trauma, but not death from aging. Their lifespans would be "indefinite," because protection from the effects of aging on health does not guarantee survival. The term "indefinite lifespans" is often considered to be technically correct by some life extensionists, as opposed to terms such as "immortality" which imply, especially in religious contexts, an inability to ever die.
