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:
“None can re-enter there—
No thief so politic,
No Satan with a royal trick
Steal in by window, chink, or hole,
To bind or unbind, add what lacked,
Insert a leaf, or forge a name,
New-face or finish what is packed,
Alter or mend eternal fact.”
—Ralph Waldo Emerson (1803–1882)
“Thou hast most traitorously corrupted the youth of the realm in erecting a grammar school.”
—William Shakespeare (1564–1616)
