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 is against Stupidity in every shape and form that we have to wage our eternal battle. But how can we wonder at the want of sense on the part of those who have had no advantages, when we see such plentiful absence of that commodity on the part of those who have had all the advantages?”
—William Booth (1829–1912)
“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)
