题目：
My secret of staying young is simple: keeping your mind awake and you will stay young all over. Take an interest in world around you, and learn at least one old thing every day. Don’t think that you are ever very old to go back to school. I know a man who entered medical college in 70. He got his degree with honors and became a famous doctor. Other man went to law school at 71 and is now a active lawyer. You may say that staying young is easy only for those live in the future. In fact, you can do it whether you care enough to try to keep your mind awake and active, and which is the only way to be always young.
