The human body has developed its millions of nerves to be highly aware of what goes on both inside and outside of it. This helps us aajust to the outside world. Without our nerves and our brain, which is a system of nerves, we couldn’t know what’s happening. But we pay for our sensitivity. We can feel pain when the slightest thing is wrong with any part of our body. The history of torture is based on the human body being open to pain. But there is a way to handle pain. Look at the Indian fakir (苦行僧) who sits on a bed of nails. Fakirs can put a needle right through an arm, and feel no pain. This ability that some humans have developed to handle pain should give us ideas about how the mind can deal with pain. The big thing in withstanding pain is our attitude toward it. If the dentist says, “This will hurts a little,” it helps us to accept the pain. By staying relaxed, and by treating the pain as an interesting sensation, we can handle the pain without falling apart. After all, although pain is an unpleasant sensation, it is still a sensafion, and sensations are the stuff of life.

What is headache What causes it What can you do about a headache What research is being done on headaches The dictionary defines headache simply 22 "a pain in the head". 23 most people mean by headache 24 (be) a pain that lasts several minutes or hours. It covers the whole head, or one side of it, or perhaps the front or the back of the head. To add to the confusion about a definition, some people call tight feeling in the head a headache. A headache is important because 25 can be the first warning of a serious condition which probably could be controlled 26 discovered early. If a person 27 (remove) the warning, day after day, with a pain-killer, he may pass the point of easy control. A headache is important also because it disturbs people, 28 (prevent) them from living a happy life. The 29 (employ) with a headache does less work. In a flash of temper he may upset his fellow 30 (guy) or customers, causing a direct or indirect loss to his organization. The mother with a headache suffers and disturbs the family.
