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.

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

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

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

Old age has deformities enough of its own. It should never add to them the deformity of vice.

I will never be an old man. To me, old age is always 15 years older than I am.

None are so old as those who have outlived enthusiasm.

I don't feel old. I don't feel anything till noon. That's when it's time for my nap.

Alas, after a certain age every man is responsible for his face.
