It is very important to stay healthy. I have a neighbor. She is an old lady, She is (几乎不) ill. She reads newspapers and learns something new on the (互联网). I often see her do taijiquan in the morning and learn (摇摆) dance in the evening. Last week a reporter from a TV (节日) asked how she kept so young and healthy. She answered with a smile, "I have a secret of staying young and (健康). It is quite easy. Keep your remind active. Learn one new thing (两次) a week. Try to do different kinds of (家务) and do sports as often as you can, Don't think you are too old to go back to school. I know a man. He entered a medical (大学) when he was 70 years old, He studied there for years. Some people may say staying(年轻) is easy only for those who live in the future. In fact, no matter how old you are, you can make it."
Please tell the (故事) to your family. It will be a good start to follow the lady's example. I hope all people will stay young and healthy.
