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:
“Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.”
—Ralph Waldo Emerson (1803–1882)
“Advice you take from me comes to you crutched
Like a beggar youth zealous for old age.”
—Allen Tate (1899–1979)
