Old minds are like old horses you must exercise them if you wish to keep them in working order.

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.

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

None are so old as those who have outlived enthusiasm.

Youth is the gift of nature, but age is a work of art.

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

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

Age is an issue of mind over matter. If you don't mind, it doesn't matter.

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

Age appears to be best in four things old wood best to burn, old wine to drink, old friends to trust, and old authors to read.
