I have a neighbor. She looks young and beautiful although she is over 70.She can do all the housework, read newspapers and learn something new on the Internet I often see her do tai chi(大极拳) in the morning and dance in the evening.Last week a reporter from a magazine asked her how she kept so young and healthy. She replied, "I have a secret for staying young and healthy. It is quite simple. Keep your mind active, be interested in the world around and 1earn at least one new thing every day.” Don't think you are too old to learn. I know a man called Jack who started to study medicine in a college when he was 70 years olD、 He studied there for 6 years and now he works in a hospital. Another man called Barry began writing at the age of 71. And now he is goodwriter. Some people may think keeping 1eamning is easy only for young people. In fact, everyone can mike it.It would be a good start to follow the old lady's example. I hope all the people will stay young and healthy.
