None are so old as those who have outlived enthusiasm.

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

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

Like everyone else who makes the mistake of getting older, I begin each day with coffee and obituaries.

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.

A man growing old becomes a child again.

Age is an issue of mind over matter. If you don't mind, it doesn't matter.

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

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

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