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:
“Thou, whose exterior semblance doth belie
Thy Soul’s immensity;
Thou best Philosopher, who yet dost keep
Thy heritage, thou Eye among the blind,
That, deaf and silent, read’st the eternal deep,
Haunted for ever by the eternal mind,—”
—William Wordsworth (1770–1850)
“We live in an age when to be young and to be indifferent can be no longer synonymous. We must prepare for the coming hour. The claims of the Future are represented by suffering millions; and the Youth of a Nation are the trustees of Posterity.”
—Benjamin Disraeli (1804–1881)
