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:
“Still let my tyrants know, I am not doomed to wear
Year after year in gloom, and desolate despair;
A messenger of Hope comes every night to me,
And offers for short life, eternal liberty.”
—Emily Brontë (1818–1848)
“His youth was distinguished by all the tumult and storm of pleasures, in which he licentiously triumphed, disdaining all decorum. His fine imagination was often heated and exhausted with his body in celebrating and deifying the prostitute of the night, and his convivial joys were pushed to all the extravagancy of frantic bacchanals.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
