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

I don't believe one grows older. I think that what happens early on in life is that at a certain age one stands still and stagnates.

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

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

How incessant and great are the ills with which a prolonged old age is replete.

Wrinkles should merely indicate where smiles have been.

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

Alas, after a certain age every man is responsible for his face.

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.
