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:
“Repose you here in rest,
Secure from worldly chances and mishaps.
Here lurks no treason, here no envy swells,
Here grow no damned drugs, here are no storms,
No noise, but silence and eternal sleep.”
—William Shakespeare (1564–1616)
“What youth or maiden conspires with the wild luxuriant beauty of Nature? She flourishes most alone, far from the towns where they reside.”
—Henry David Thoreau (1817–1862)
