I think bungee jumping is a good example of such an activity. Yet jump from a high place(maybe a bridge or a hot-air balloon (气球) 200 meters above the ground with an elastic rope ( 弹力绳 ) to your ankles (踝). You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. It is said that 2, 000, 000 people around the world have now tried bungee jump-ing. Most people think that other activities, such as jumping from the tall buildings and diving into the sea from the top of high rocks (岩石) are as dangerous as bungee jumping.
Why do people take part in such activities as these? Some scientists think it is because life in modern societies has become safe and boring. Now life has little excitement. They buy food in shops and there are doctors and hospitals to look after them if they are ill. The answer for some of these people is to look for danger in activities as bungee jumping.
