After thirty, a body has a mind of its own.

There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.

Age is not a particularly interesting subject. Anyone can get old. All you have to do is live long enough.

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

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