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:
“In spite of all the learned have said,
I still my old opinion keep;
The posture, that we give the dead,
Points out the soul’s eternal sleep.
Not so the ancients of these lands—
The Indian, when from life released,
Again is seated with his friends,
And shares again the joyous feast.”
—Philip Freneau (1752–1832)
“From you have I been absent in the spring,
When proud pied April, dressed in all his trim,
Hath put a spirit of youth in every thing,
That heavy Saturn laughed and leaped with him.”
—William Shakespeare (1564–1616)
