It seems to be strange to you there is a blind spot(点) on the eyes. Here is an interesting experiment that can make something disappear, when one eye is open.
　　Make a card about the size of a postcard and write two English letters L and R on it, L on the left and R on the right. First, hold the card about 80 cm away and you see both the letters. 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 of the letter falls on the blind spot, it won’t be seen. That is why either of the letters disappears.

Now and then we all get ill. Then we usually go to see a doctor. Doctors know a lot about what makes us ill. They may give us something to take. The medicine often makes us well again.

But sometimes the doctor’s medicine doesn’t work. A sick person does not get well. The pain will not go away. This happened to one man. He was in hospital, but he was not getting well. Then he found a new “doctor” inside himself. This “doctor” was his own sense of humor(幽默感). He saw funny films. He read funny books. And something wonderful happened. Laughing took away his pain. Then he was able to sleep and rest. His own happy feeling was his best “medicine”. His doctor thought so, too.

Another man was ill, and he had a terrible pain in his back. The doctors could not stop it from hurting. So the man began to “picture” his pain. In his head he “drew” a picture of a dog. He imagined it as a real dog. And he made friends with the dog. And his pain went away!

These stories may surprise you. But more and more people are getting well in this way. So visit the “doctor” inside you and you can stay happy and well.
