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:
“Celestial Cupid her fam’d son advanc’t,
Holds his dear Psyche sweet intranc’t
After her wandring labours long,
Till free consent the gods among
Make her his eternal Bride,
And from her fair unspotted side
Two blissful twins are to be born,
Youth and Joy; so Jove hath sworn,”

Went to walk in a grim forest.
There he met an assassin”
