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:
“What seems to be, is, to those to whom
It seems to be, and is productive of the most dreadful
Consequences to those to whom it seems to be, even of
Torments, despair, eternal death.”
—William Blake (1757–1827)
“Care keeps his watch in every old man’s eye,
And where care lodges, sleep will never lie;
But where unbruisèd youth with unstuffed brain
Doth couch his limbs, there golden sleep doth reign.”
—William Shakespeare (1564–1616)
