At 20, the will reigns; at 30, the wit; and at 40, the judgement.

If youth only knew; if age only could!

We are born naked, wet and hungry. Then things get worse!

Aging is mandatory. Maturity is optional.

You are only young once, but you can stay immature indefinitely.

Never trust anyone over thirty.

Age is a number and mine is unlisted.

Age is a very high price to pay for maturity.

Youth is a disease from which we all recover.

It's sad to grow old, but nice to ripen.

It's not how old you are, it's how hard you work at it.

The older you get, the stronger the wind gets - and it's always in your face.

Women over thirty are at their best, but men over thirty are too old to recognize it.

There is still no cure for the common birthday.
