Do you tend to get stressed out behind the wheel?
坐在駕駛位置上的你是否感到壓力非常大呢？
That might not be a bad thing.
也許這并不是壞處。
Researchers have discovered that teenager drivers who have a high sensitivity to stress actually have lower rates of car accidents than their mellow friends.
研究人員們發(fā)現(xiàn)壓力敏感的青年駕駛員相比別的司機(jī)實(shí)際上遇到車禍的幾率要小。
Car crashes are the leading cause of death for teenagers, so teen driving is a legitimate public health issue that deserves a lot of study.
青少年非正常死亡最多的便是車禍造成，因此青少年駕駛是一種還是有很多值得研究的法律意義上公眾健康問題。
To create a stressful situation in the lab, scientists administered a math test to 40 teenagers, all of whom had recently gotten their drivers'licenses.
為了在實(shí)驗(yàn)室內(nèi)制造出壓力環(huán)境，科學(xué)家們對40多名最近才拿到駕照的青少年進(jìn)行了數(shù)學(xué)測試。
The researchers measured the teens'level of the stress hormone hormone cortisol after the math quiz.
研究人員在數(shù)學(xué)測驗(yàn)后測量了這些青少年的壓力荷爾蒙皮質(zhì)醇水平。
The higher the cortisol level, the more sensitive an individual is to a pressurized situation.
皮質(zhì)醇水平越高,個(gè)人對于壓力增加的情況越是敏感。
The researchers then tracked the teens for 18 months.
研究人員們之后又對青少年進(jìn)行了18個(gè)月的跟蹤檢測。
And cameras mounted inside their cars documented their driving behavior.
而且安裝在汽車內(nèi)部的攝像頭記錄了他們的駕車行為。
Turned out that the teens who had a lower response to stress actually had higher rates of crashes and near crashes than did those with higher stress sensitivity.
結(jié)果顯示抗壓能力比較強(qiáng)的青年們實(shí)際上比那些對壓力敏感的人更容易出現(xiàn)事故或者事故未遂。
Calm confidence can be a valuable attribute in some situations.
冷靜自信在某些情況下是有顯著利用價(jià)值的品質(zhì)。
But behind the wheel perhaps the safer teen driver is just a bit jangled.
但是就開車這事來說，或許還是神經(jīng)質(zhì)的年輕司機(jī)更安全。
