The worst old age is that of the mind. But when I got to be 21, I was astonished at how much he had learned in 7 years. The prosperity of a country is in accordance with its treatment of the aged. I promise to keep on living as though I expected to live forever. Nobody grows old by merely living a number of years.
People grow old by deserting their ideals.
Years may wrinkle the skin, but to give up wrinkles the soul. Nothing is more disgraceful than that an old man should have nothing to show to prove that he has lived long, except his years. When a man is old enough to do wrong he should be old enough to do right also. No wise man ever wished to be younger. Most people say that as you get old, you have to give up things.
