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)
“In youth the human body drew me and was the object of my secret and natural dreams. But body after body has taken away from me that sensual phosphorescence which my youth delighted in. Within me is no disturbing interplay now, but only the steady currents of adaptation and of sympathy.”
—Haniel Long (1888–1956)
