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:
“Make us eternal truths receive,
And practice all that we believe:
Give us thyself, that we may see
The Father and the Son, by thee.”
—Charlemagne (1559?–1634)
“I always was of opinion that the placing a youth to study with an attorney was rather a prejudice than a help.... The only help a youth wants is to be directed what books to read, and in what order to read them.”
—Thomas Jefferson (1743–1826)
