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:
“It has been rightly said that nothing is unimportant, nothing powerless in the universe; a single atom can dissolve everything, and save everything! What terror! There lies the eternal distinction between good and evil.”
—Gérard De Nerval (1808–1855)
“He that hath a beard is more than a youth, and he that hath no beard is less than a man; and he that is more than a youth is not for me, and he that is less than a man, I am not for him.”
—William Shakespeare (1564–1616)
