Extreme pressure

When I start to think about this question, my first thought was brave and confidence. This two qualities has to have it if you want to do the stuff that stakes were high. When I went to Taipei to watch a musical, I remember they have swing some people from one side to the other side and it's really high when they do this, I was very enjoy it because they didn't have fail the performance. Now when I thought about it,  I don't even know how much brave and confidence they need to have to do this action, because if they fail during the performance, they might just fall right to the ground and died (I didn't remember they have any net under, but there's some cushion under it). If the performer is me, I will always be worry about how dangerous it is and think what if I fail and died. I think the people who like to do action that the risks are high are really brave and is not scare to die, also they must be really confidence about their performance, they believe that they will not fail it. Overall, I'm very impressive about them that don't afraid about the outcome if they fail to do it.
