19.The Science of Risk-SeekingSometimes We decide that a little unnecessary danger is worth it because when we weigh the risk and the reward,the risk seems worth tasking.(71)F Some of us enjoy activities that would surprise and scare the rest of us.Why?Experts say it may have to do with how our brains work.
The reason why any of us take any risks at all might have to do with early humans.Risk-takers were better at hunting,fighting,or exploring.(72)CAs the quality of Risk-taking was passed from on ration to the next,humans ended up with a sense of adventure and a tolerance for risk.
So why aren't we all jumping out of airplanes then?Well,even 200,000years ago,too much risk-taking could get one Killed.A few daring survived,though,along with a few stay-in-the-cave types.As a result,humans developed a range of character types that still exists today.So maybe you love car racing,or maybe you hate it. (73)A
No matter where you are on the risk-seeking range,scientists say that your Willingness to take risks increases during your teenage years.(74)ETo help you do that,your brain increases your hunger for new experiences.New experiences often mean taking some risks,so your brain raises your tolerance for risk as well.
Mean taking some risks,so your brain raisers your tolerance for risk as well.
(75)G For the risk-seekers a part of the brain related to pleasure becomes active,while for the rest of us,a part of the brain related to fear becomes active.
As experts continue to study the science of risk-seeking,we'll continue to hit the mountains,the waves or the shallow end of the pool.

C.Being better at those things meant a greater chance of survival.

E.This is when you start to move away from your family and into the bigger world.
F.However,we are not all using the same reference standard to weigh risks and rewards.
G.New brain research suggests our brains work differently when we face a nervous situation.
分析 文章讲述了人们喜欢冒险的来源和科学依据.人们都喜欢冒险,因为风险也意味着回报.生活中人们喜欢做一些让别人意外和害怕的事,这和人的大脑有关.早期的先民中,那些敢冒险的人在狩猎,战斗或探险中表现更优秀.当然,也有不喜欢冒险的人,就像赛车,有人喜欢有人不喜欢.科学家们还说,冒险的想法和一个人的年龄有关,大脑在提高你冒险的渴望的同时也提高你对风险的承受能力.
