More and more people around the world are joining in dangerous sports. Some people climbed the highest mountains, some traveled into unknown parts of the world, some sit in small boats across the largest sea. Now some people begin to look for a new excitement.
Bungee jumping (蹦极) and motorcycle (摩托车)race are quite dangerous sports. Bungee jumping only lasts a few minutes or even seconds. You jump from a high place 200 meters above the ground, and there is a rubber band(带)tied to your legs. You fall down and the rubber band pulls you up. About 2 000 000 people around the world have tried bungee jumping.
Why people join in these dangerous sports? Some scientists say that it is because modern life has become safe and it is not interesting.In the past, people lived in danger. They had to go out and look for food, and life was like a fight and was interesting.
Nowadays many people think that there is little excitement in life. They live and work in safe places, buy food in shops, and there are doctors and hospitals to look after them if they become ill.
