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:
“Never has any one been less a priest than Jesus, never a greater enemy of forms, which stifle religion under the pretext of protecting it. By this we are all his disciples and his successors; by this he has laid the eternal foundation-stone of true religion; and if religion is essential to humanity, he has by this deserved the Divine rank the world has accorded him.”
—Ernest Renan (1823–1892)
“The youth of an art is, like the youth of anything else, its most interesting period. When it has come to the knowledge of good and evil it is stronger, but we care less about it.”
—Samuel Butler (1835–1902)
