Many young people these days are interested in extreme sports, which mean very dangerous activities that need speed, height, or a high level of physical exertion(努力). Bungee jumping, snowskating, parkour and surfing are very popular extreme sports, but mountain climbing might be the first.

In 1985, two British young men, Joe Simpson and Simon Yates became the first west faces to climb the 6344-meter Siula Grande in the Andes(安第斯山脉). On the way down, Simpson fell and broke his leg, then he slipped(滑) down and lost connection with his friend. Yates had to get for help. Simpson fell more than 100 feet and landed on a bridge of ice. Finally he crawled(爬) for three days without food or water, until he reached the camp.

On April 26, 2003, when Aron Rolston was climbing alone in Utah, his arm was caught under a 360-kilo rock and he couldn’t move. After five days of waiting for help, the 28-year-old American ran out of water and finally he cut off half his right arm with a small knife to free himself. He also bandaged(包扎) himself in order not to lose too much blood. In 2004, he wrote a book named Between a Rock and a Hard Place. “In this book,” Aron said, “I want to tell the readers the importance of making good decisions, and of being in control of one’s life.”
