Why Take Risks?

What does Krakauer say about why mountain climbers take such risks? Think of the kinds of risks people take, both physical and otherwise. Do his conclusions apply to other risk takers as well? In your own experience, when you have taken risks or seen others take risks, what do you think the reasons were? Do they match up with what Krakauer says?

• Krakauer says that mountain climbers take risks because nothing that happens during mountain climbing can be predicted, so we cannot prepare for all of the diasaters that might happen - we can only do some basic preparations and precautions.
• Kinds of risks that people take mainly include physical and mental risks. Physical risks include extreme pressure and strain on your body to challenge both your physical and mental limitations. Mental risks include decision making. For example, in the stock market, when you make a good decision and buy the right stock and sell at the right time, then you will benefit and gain a lot of money. However, when you make the wrong decision, then you might loose a large amount of money. 
• I believe that Krakauer's conclusions also apply to other risk takers. Actually, everyone is at risk, because you might die the next second even though you're just sitting down and doing nothing. I totally agree with this, so I believe that we should live our life. 
• Some reasons for taking risks include the satisfaction that one get's after they completed the challenge, or when they overcome a fear. Peer pressure may also be an important reason. For example, if everyone else are brave enough to do something, then you will also want to do it to prove that you are a part of their group.
