My secret of staying young is quite simple：devote your attention to the part of you that’s young and growing—your brain. Keep your mind awake and you will stay young all over. These are exciting times. Take an interest in the world around you，and make a point of learning one new thing every day.
No matter how old you are ，it’s not too late to make your life more interesting. I know a housewife without knowledge in the past who made herself into an excellent industrial designer. I know an old electrical engineer who has become a highly paid artist.
Get over the idea the you are too old to go back to school. I know a man who entered a medical college at 70. He got his degree with honors and became a famous doctor. Another man went to a law school at 71 and now is an active lawyer.
