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:
“By choice they made themselves immune
To pity and whatever moans in man
Before the last sea and the hapless stars;
Whatever mourns when many leave these shores;
Whatever shares
The eternal reciprocity of tears.”
—Wilfred Owen (1893–1918)
“I am admonished in many ways that time is pushing me inexorably along. I am approaching the threshold of age; in 1977 I shall be 142. This is no time to be flitting about the earth. I must cease from the activities proper to youth and begin to take on the dignities and gravities and inertia proper to that season of honorable senility which is on its way.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
