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

A diplomat is a man who always remembers a woman's birthday but never remembers her age.

Every man over forty is a scoundrel.

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.

Growing old is no more than a bad habit which a busy person has no time to form.

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

A man growing old becomes a child again.

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

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

None are so old as those who have outlived enthusiasm.
