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.

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

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.

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

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

Every man over forty is a scoundrel.

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

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