We do not quit playing
because we grow old.

We grow old
because we quit playing.
   Oliver Wendell Holmes

Wisdom does not automatically come with old age.
Nothing does---except wrinkles. It's true, some wines improve with age,
but only if the grapes were good in the first place.
    Dear Abby

You may search my time-worn face,
You'll find a merry eye that twinkles.
I am NOT an old lady
Just a little girl with wrinkles!
   Edythe E. Bregnard

Age is mostly a matter of mind.
If you don't mind,
it doesn't matter.

The older the fiddle,
the sweeter the tune.
   English proverb

Years may wrinkle the skin,
but to give up enthusiasm
wrinkles the soul.
   Samuel Ullman
