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)
“Sprung from the West,
He drank the valorous youth of a new world.
The strength of virgin forests braced his mind,
The hush of spacious prairies stilled his soul.
His words were oaks in acorns; and his thoughts
Were roots that firmly gript the granite truth.”
—Edwin Markham (1852–1940)
