(For my practice for English examination and this might be not my honest opinion.)
Why do you think some people are attracted to dangerous sports or other activities?
I have often seen people who devoted themselves to dangerous sports or activities in this year through watching Olympic on TV. Some athletes performed high jumps with complicated technics. Although I hate to do dangerous things because I am timid and I don’t want to get injured. However, I can understand that there are some people who like dangerous sports and activities for the following two reasons.
Firstly, I believe that they want to overcome themselves physically and mentally through dangerous sports and activities. Actually, those people have to be afraid of many things during their performances such as breaking bones and there is even possibility to die depending on the situation. In general, although ordinary people like me tend to avoid such risks, there are some people who want to take risks positively, and enjoy overcoming them. Then, after completing their own mission, they can feel satisfied and proceed their next stages which are more difficult to overcome. As a result, we can say that they just enjoy the process and the routine. This is one reason why they want to take risks in spite of dangerous things.
Secondly, in my opinion, the chemical substance like adrenalin may affect their action. Some researchers claim that the adrenalin is released when we are in dangerous situation such as fighting against foes in a war and also it can motivate us. In fact, all people have this substance in our bodies as our innate abilities because animals need to fight against other animals in order to defend ourselves and our family. Of course, humans are no exception. The more people are afraid of something, the more the adrenalin will be released. This is the method why some people devote themselves to those dangerous sports and activities.
To sum up, for the following those reasons, overcoming difficulties is their satisfaction, and the chemical substance such as adrenalin affects their behavior, I understand that some people devote themselves to dangerous sports and activities.
