While one finds company in himself and his pursuits, he cannot feel old, no matter what his years may be.

To resist the frigidity of old age, one must combine the body, the mind, and the heart. And to keep these in parallel vigor one must exercise, study, and love.

Old age is the most unexpected of all the things that can happen to a man.

No one can avoid aging, but aging productively is something else.

If you haven't turned rebel by twenty you've got no heart if you haven't turned establishment by thirty you've got no brains!
