　　Fear can be fun. Many young people queue up to ride very fast and scary roller coasters（过山车）screaming but enjoying themselves. Other people like to read “goose bumps （鸡皮疙瘩）” books or watch horror movies at night, scared to death but feeling excited. Why do people like being scared?

　　Fear is an ancient way of surviving. Being scared makes animals, including humans escape from danger and save themselves. It is because of fear that we have lived through millions of years of evolution. Those who lacked a strong fear response were more likely to be killed, leaving the more fearful and careful to pass their genes onto the next generation.

　　How do scientists explain why shaking over such scary things is fun? “Some kids will go to a scary movie and love it and laugh over it, others will feel anxious and hide their faces and some won't even set foot in the cinema," said Ned Kalin, a US scientist. "Which kind of person you are depends partly on experiences you've had and partly on your genes."

　　What happens in the brain when something frightens you? Nerves that begin at the eyes and ears lead to a part of the brain called the amygdala. When you suddenly see a snake, for example, the amygdala makes you freeze, perspire, have a quickened heartbeat, or run very fast. However, seeing the snake also uses another part of the brain, the cortex. It analyzes the situation, and if it finds that the snake is only made of rubber it tells your heart and the rest of your body to calm down. Think of the amygdala as the engine and the cortex as the brake.
