Then close your right eye and look at the letter R only with your left eye. And now. as you move the card slowly towards you. you'll find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again, Now do the same experiment with your left eye closed, you'll find the letter R disappearing,
Why does the letter disappear? It is because there is a blind spot on the eye. When the image（影像） or the letter falls on the blind spot, it won't be seen. That is why either of the letters disappears.

It is very important to stay healthy. I have a neighbor. She is an old lady. She can do all the housework, 16 newspapers, watch TV and search on the Internet to learn something new. I often see 17 do taijiquan in the morning and dance in the evening. She looks young and beautiful 18 she is over seventy. Last week a reporter from a magazine interviewed her and asked 19 she kept so young and healthy. She replied with a smile:
I have a secret of staying young and healthy. It is quite 20 . Keep your mind active, take an interest in the world 21 you, and learn at least one new thing every day. Try to do different kinds of housework and do sports as 22 as you can. Don’t think you are too old to go back to 23 . 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 24 tennis. Some people may say staying young 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 story to your family. It would be a good start to 25 the lady’s example. I hope all people will stay young and healthy.
