Youth is the gift of nature, but age is a work of art.

Old age comes on suddenly, and not gradually as is thought.

I don't believe one grows older. I think that what happens early on in life is that at a certain age one stands still and stagnates.

Forty is the old age of youth, fifty is the youth of old age.

You can't help getting older, but you don't have to get old.

Youth is when you're allowed to stay up late on New Year's Eve. Middle age is when you're forced to.

Forty is the old age of youth fifty the youth of old age.

How incessant and great are the ills with which a prolonged old age is replete.

None are so old as those who have outlived enthusiasm.
