You are as young as your self-confidence, as old as your fears: as young as your hope, as old as your despair.
Middle age is youth without levity, and age without decay.
Forty is the old age of youth: fifty the youth of old age.
Old age is like a plane flying through a storm. Once you're aboard, there's nothing you can do.
You can't help getting older, but you don't have to get old.
Old age, believe me, is a good and pleasant thing. It is true you are gently shouldered off the stage, but then you are given such a comfortable front stall as spectator.
