The Science of Risk-Seeking
Sometimes We decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth tasking. 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. As 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 200,000 years 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.
No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. To 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.
,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.
A. It all depends on your character. B. Those are the risks you should jump to take. C. Being better at those things meant a greater chance of survival. D. Thus, these well-equipped people survived because they were the fittest. 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. |

But back in the early days of computers, a woman named Grace Hopper was part of a team that discovered the very first computer bug.
{#blank#}2{#/blank#} She had been invited to help program a new computer, the job of which was to quickly deal with the math problems ships used to find their way.{#blank#}3{#/blank#} Then it translated the patterns of holes into the math problems it was supposed to solve.
One afternoon in 1947 Hopper and her team were running a program. But the computer wasn't giving them the right results.{#blank#}4{#/blank#} They finally ended up taking the computer apart, looking for problems. What did they find? It was a moth (飞蛾)! The moth was blocking some of the holes in the paper—{#blank#}5{#/blank#} Some people think Hopper was the first person to use the word “debug” to mean “get rid of the problems in a computer”.
A. What could be wrong? B. Hopper was a mathematician. C. Who had operated the computer? D. Hopper was a hardworking scientist. E. She thought it was funny that it was a real one. F. Or you got an error message when you tried to go to a website. G. The computer worked by reading instructions from a long piece of paper with holes in it. |
