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

Old minds are like old horses you must exercise them if you wish to keep them in working order.

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

None are so old as those who have outlived enthusiasm.

A man growing old becomes a child again.

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

Old age is like everything else. To make a success of it, you've got to start young.

Aging is not lost youth but a new stage of opportunity and strength.

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

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