Eternal Youth. That is what we strive to attain. Watch Forever Young … by Alphaville.
This does not mean immortality since accidents, violence, severe illness, all those can strike the young as well as the old.
Eventually, we may die. But we’ll die young!
It does mean youthful enjoyment of life. Physical activity and mental prowess. Exploring the world like a child. Living with a body which is vigorous and self-healing and therefore basically disease free.
It also means, for most of us, a long life. As with age and life experience does come wisdom. With wisdom comes the avoidance of self-destructive and excessively risky behavior.
