Secret of Staying Young
My secret of staying young is 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 ail over. These are exciting times. Take an interest in the world around you, and make a point of learning at least 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 that you are over too old to go back to school. I know a man who entered medical college at 70. He got his degree with honours and became a famous doctor. An other man went to law school at 71 and now is an active lawyer.
No matter how old people are, staying young is easy for these who live in the future. You can clo it if you are active enough to try. Keep your mind awake and active: that's the only youth elixir.
