Now it's line that 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 adjust to the world. Without our nerves—and our brain, which is a bundle of nerves—we wouldn'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 your 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 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 hurt 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 sensation, and sensations are the stuff of life.
The purpose of this passage is mainly to tell us ______.

A. that pain is good for us
B. to stop taking the "needle" at the dentist's
C. how to handle pain
D. how to avoid torture
