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:
“For Banquo’s issue have I filed my mind;
For them the gracious Duncan have I murdered;
Put rancors in the vessel of my peace
Only for them; and mine eternal jewel
Given to the common enemy of man,
To make them kings, the seeds of Banquo kings!”
—William Shakespeare (1564–1616)
“When the merry bells ring round,
And the jocund rebecks sound
To many a youth and many a maid,
Dancing in the chequered shade;
And young and old come forth to play
On a sunshine holiday,”
—John Milton (1608–1674)
