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:
“And our sov’reign sole Creator
Lives eternal in the sky,
While we mortals yield to nature,
Bloom awhile, then fade and die.”
—Unknown. “Hail ye sighing sons of sorrow,” l. 13-16, Social and Campmeeting Songs (1828)
“Do not think the youth has no force, because he cannot speak to you and me. Hark! in the next room his voice is sufficiently clear and emphatic. It seems he knows how to speak to his contemporaries. Bashful or bold then, he will know how to make us seniors very unnecessary.”
—Ralph Waldo Emerson (1803–1882)
