And so I get this question all the time from parents, and they ask me, "Would you let your own child play football?"
家長們總是問我這樣一個問題，他們問我，“你會讓你自己的小孩兒打橄欖球嗎？”
Or, "Should I let my child play soccer?"
或者“我應該讓我小孩兒踢足球嗎？”
And I think that as a field, we're a long way from giving an answer with any kind of confidence there.
我認為從一個學科領域的角度來講，我們遠沒有信心在此回答這樣一個問題。
So I look at that question from a bit of a different lens, and I want to know, how can we prevent concussion?
所以我從另外一個角度思考了這個問題，我想知道，我們如何預防腦震蕩？
Is that even possible? And most experts think that it's not,
這能做到嗎？絕大多數專家認為不能，
but the work that we're doing in my lab is starting to reveal more of the details around concussion so that we can have a better understanding.
但我的實驗室目前所從事的研究，將揭示腦震蕩的更多細節，從而我們會對腦震蕩有更深刻的認知，
The reason we're able to prevent skull fracture with helmets is because it's pretty simple.
戴頭盔能預防顱骨骨折的原因非常簡單，
We know how it works. Concussion has been much more of a mystery.
我們知道這一原理，而腦震蕩至今仍是未解之謎。
So to give you a sense of what might be happening in a concussion,
為了讓在座各位對腦震蕩有更直觀的了解，
I want to show you the video here that you see when you type into Google, "What is a concussion?"
我要放一段影片，你可以在谷歌搜索如下字樣，What is a concussion?
The CDC website comes up, and this video essentially tells the whole story.
然后打開CDC（美國疾病控制與預防中心）網頁，網頁上的這段視頻就會講述腦震蕩的成因。
What you see is the head moves forward, the brain lags behind, then the brain catches up and smashes into the skull.
你可以看到：頭部向前移動，腦組織移動延后，接著腦組織跟了上來也向前移，撞向顱骨。
It rebounds off the skull and then proceeds to run into the other side of the skull.
被顱骨彈回，然后向另一邊顱骨撞去。
And what you'll notice is highlighted in this video from the CDC, which I'll note was funded by the NFL,
CDC影片中高亮的那部分，順帶說一下，這一影片由NFL（美國國家橄欖球聯盟）資助，
is that the outer surface of the brain, where it was to have smashed into the skull,
是腦組織的外部邊緣，這部分腦組織之前曾撞向顱骨，
looks like it's been damaged or injured, so it's on the outer surface of the brain.
看起來它受到了損傷，所以高亮部分是在腦組織的外部邊緣。
And what I'd like to do with this video is to tell you that there are some aspects
我放這段影片，是為了告訴各位，這段影片的部分內容，
that are probably right, indicative of what the scientists think happens with concussion,
或許確實正確地表述了科學家對腦震蕩的理解，
but there's probably more that's wrong with this video.
但這段影片更多地方是錯誤的。
