Biological Immortality
Certain exotic organisms do not seem to be subject to aging and can live indefinitely. Examples include Tardigrades and Hydras. That is not to say that these organisms cannot die, merely that they only die as a result of disease or injury rather than age-related deterioration (and that they are not subject to the Hayflick limit).

Famous quotes containing the words biological and/or immortality:
“Much of the ill-tempered railing against women that has characterized the popular writing of the last two years is a half-hearted attempt to find a way back to a more balanced relationship between our biological selves and the world we have built. So women are scolded both for being mothers and for not being mothers, for wanting to eat their cake and have it too, and for not wanting to eat their cake and have it too.”
—Margaret Mead (1901–1978)
“The aim of every artist is to arrest motion, which is life, by artificial means and hold it fixed so that a hundred years later, when a stranger looks at it, it moves again since it is life. Since man is mortal, the only immortality possible for him is to leave something behind him that is immortal since it will always move. This is the artist’s way of scribbling “Kilroy was here” on the wall of the final and irrevocable oblivion through which he must someday pass.”
—William Faulkner (1897–1962)
