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

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.

None are so old as those who have outlived enthusiasm.

Age appears to be best in four things old wood best to burn, old wine to drink, old friends to trust, and old authors to read.

What most persons consider as virtue, after the age of 40 is simply a loss of energy.

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

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

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

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