<< People sometimes feel like taking unnecessary risk. As for me, I sometimes enjoy horse recing at the risk of cousing financial difficulty. Why people dare to do what involves risk? From my experinece, there are two reasons for people to participate in dangerous sports or other dangerous activities. First reason is that taking a risk itself rises our body tense which cause physical comfort. When people are runing a risk of something like bunkruptcy, injury, and even their life, they feel anxious and are very careful to manage to deal with the situation. They concentrate on everthing connected with the situation. Therefore, high tension and concentration make us excited and feel comfortable. In fact, when I bet money on a race, I concentrate on watching the rece much more and the race excites me. I feel comfortable to watch the race feeling anxious whether or not I lose money. Second reason is that dangerous activity tend to have possibility to make benefit. In this case, people weigh the risk against the benefit which they would gain, and they chose to run the risk. For instance, those who run the grave risk in inbusiness can usually be applied to the second type. They might think the failure to win the gamble. However, after all, they conclude that they would succeed in making benefit in this gamble even if others seems that the possibility of success is neary zero. In conclusion, I think that people are sometimes willing to be exposed themselves to dangerous situation in vain in order to pursue their physical comfort or more money or other valuable things.
