Eternal youth is the concept of human physical immortality free of aging. The youth referred to is usually meant to be in contrast to the depredations of aging, rather than a specific age of the human lifespan.
So far, achieving eternal youth remains beyond the capabilities of science. However, much research is currently being conducted in the sciences of genetics which may allow manipulation of the aging process at some time in the future.
Eternal youth is common in mythology, and it remains a popular theme in fiction.
Famous quotes containing the words eternal and/or youth:
“Wherever there are walls I shall inscribe this eternal accusation against Christianity upon them—I can write in letters which make even the blind see ... I call Christianity the one great curse, the one great intrinsic depravity, the one great instinct for revenge for which no expedient is sufficiently poisonous, secret, subterranean, petty—I call it the one immortal blemish of mankind....”
—Friedrich Nietzsche (1844–1900)
“Genius goes around the world in its youth incessantly apologizing for having large feet. What wonder that later in life it should be inclined to raise those feet too swiftly to fools and bores.”
—F. Scott Fitzgerald (1896–1940)
