None are so old as those who have outlived enthusiasm.

Aging is not lost youth but a new stage of opportunity and strength.

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.

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

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

Like everyone else who makes the mistake of getting older, I begin each day with coffee and obituaries.

What most persons consider as virtue, after the age of 40 is simply a loss of energy.

Old age has deformities enough of its own. It should never add to them the deformity of vice.

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