Immortality
The terms "immortality" and "eternal youth" are often used as synonyms for "indefinite lifespan", but they carry connotations from their other contexts which science has deemed to be impossible. That is, immortal means "incapable of dying". Eternal implies guaranteed existence for eternity, and in this context is also implausible because of entropy. Even if cures were found for all the degenerative diseases, and effective treatments were developed for all the processes of aging, so that bodies could be maintained as easily as cars can be repaired, people would still be killed in accidents, slain in wars, choosing to die, etc. The term indefinite lifespan represents this more achievable state of affairs, because it merely implies freedom from death by age or infirmity. The use of the term is also sometimes favored for reasons of linguistic aesthetics, in the same way that the term birth control is preferred to "birth prevention" or "birth elimination" which both imply, as does 'immortality', that the choice is one-time only and has permanent consequences, whereas the point of 'indefinite lifespans', like the point of 'birth control', is to gain the opportunity to lead one's life in a more conscious and deliberate manner.

Famous quotes containing the word immortality:
“If God bestowed immortality on every man then when he made him, and he made many to whom he never purposed to give his saving grace, what did his Lordship think that God gave any man immortality with purpose only to make him capable of immortal torments? It is a hard saying, and I think cannot piously be believed. I am sure it can never be proved by the canonical Scripture.”
—Thomas Hobbes (1579–1688)
“The moment the doctrine of the immortality is separately taught, man is already fallen. In the flowing of love, in the adoration of humility, there is no question of continuance. No inspired man ever asks this question, or condescends to these evidences. For the soul is true to itself, and the man in whom it is shed abroad cannot wander from the present, which is infinite, to a future which would be finite.”
—Ralph Waldo Emerson (1803–1882)
“But even suppose blood should flow. Is there not a sort of blood shed when the conscience is wounded? Through this wound a man’s real manhood and immortality flow out, and he bleeds to an everlasting death. I see this blood flowing now.”
—Henry David Thoreau (1817–1862)
