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:
“The longest day must have its close—the gloomiest night will wear on to a morning. An eternal, inexorable lapse of moments is ever hurrying the day of the evil to an eternal night, and the night of the just to an eternal day.”
—Harriet Beecher Stowe (1811–1896)
“Love, whose power youth feels, is not suitable for the elderly, just as little as anything that presupposes productivity. It is rare that productivity lasts through the years.”
—Johann Wolfgang Von Goethe (1749–1832)
