Age is just a number. It's totally irrelevant unless, of course, you happen to be a bottle of wine.

Age wrinkles the body. Quitting wrinkles the soul.
Age is no barrier. It's a limitation you put on your mind.
Age is not a disease... it is strength and survivorship, triumph over all kinds of vicissitudes and disappointments, trials and illnesses.
Age is no guarantee of maturity.
Age is a question of mind over matter. If you don't mind, it doesn't matter.
You are never too old to set another goal or to dream a new dream.
Age does not protect you from love, but love, to some extent, protects you from age.
The old believe everything; the middle-aged suspect everything; the young know everything.

Age is not a particularly interesting subject. Anyone can get old. All you have to do is live long enough.
Age is something that doesn't matter, unless you are a cheese.
Age is an issue of mind over matter. If you don't mind, it doesn't matter.
Age is a case of mind over matter. If you don't mind, it don't matter.
Age is not how old you are, but how many years of fun you've had.
Age is a case of mind over matter. If you don't mind, it doesn't matter.

As we grow old, the beauty steals inward.

Do not regret growing older. It is a privilege denied to many.

The old believe everything, the middle-aged suspect everything, the young know everything.
