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:
“No poetic phantasy
but a biological reality,
a fact: I am an entity
like bird, insect, plant
or sea-plant cell;
I live; I am alive.”
—Hilda Doolittle (1886–1961)
“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)
