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

Every man over forty is a scoundrel.

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.

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

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

Bashfulness is an ornament to youth, but a reproach to old age.

You can't help getting older, but you don't have to get old.

I don't feel old. I don't feel anything till noon. That's when it's time for my nap.

Age is a very high price to pay for maturity.

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