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:
“Hail holy Light, of spring of Heav’n first-born,
Or of th’ Eternal Coeternal beam
May I express thee unblam’d? since God is Light,
And never but in unapproached Light
Dwelt from Eternitie, dwelt then in thee,
Bright effluence of bright essence in create.
Or hear’st thou rather pure Ethereal stream,
Whose Fountain who shall tell?”
—John Milton (1608–1674)
“If the quick fire of youth light not your mind,
You are no maiden, but a monument.
When you are dead, you should be such a one
As you are now; for you are cold and stern.”
—William Shakespeare (1564–1616)
