Keep your mind active, take an interest in the world 6 you, and learn at least one new thing every day. Try to do different kinds of housework and do sports as 7 as you can. Don't think you are too old to go back to 8 . I know a man who entered a medical college when he was 70 years old. He studied there for 6 years and now he is a doctor. Another man went to a tennis school at the age of 71 and now he is good at 9 tennis. Some people may say staying young is easy only for those who live in the future.
