1、Four short words sum up what has lifted most successful individuals above the crowd: a little bit more.-author-dateA-pill-to-forgetI couldnt get my body to stop shakingI couldnt get my body to stop shaking. I was trembling constantly, trembling and.memories of it would just come back, reoccurring ov

2、er, over and over.Beatriz Arguedas is a subway conductor, driving her normal route on the Red Line in Boston, when one of her worst fears came to pass.For Im entering, one of the busiest stations, a man jumped in front of my train to commit suicide.(Entering, path three .)You actually saw him jumpin

3、g?I saw him jump, we, sort of made eye contact. And then I felt the thud, found him hitting the train, and then the crackling sound underneath the train. And then, of course, my heart started thumping.She came into our, into our emergency room afterwards, very upset, no physical injury, entirely, a

4、psychological trauma.Doctor Roger Pitman is a psychiatrist at Harvard Medical School who has studied and treated patients with Post-traumatic Stress Disorder, or PTSD for 25 years.They are caught up so much with this past event that is constantly in their mind. They are living in it over and over an

5、d over as if its happening again, and they just cant get involved in real life.When Beatriz arrived in the emergency room, Pitman enrolled her in an experimental study of a drug called propranolol, a medication commonly used for high-blood pressure and unofficially for stage fright. Pitman thought i

6、t might do something almost magical: Trick Beatrizs brain into making a weaker memory of the event she had just experienced. In the study that is still underway, half the subjects get propranolol, half get placebo.Did you know whether she got the drug?No, I didnt.You have no idea?We have no idea, an

7、d she has no idea.Till this day?And well have it for another two years.Almost she finds out .If Pitman is right, the results could fundamentally change the way accident victims, rape victims, even soldiers are treated after they experienced trauma. The story begins with some surprising discoveries a

8、bout memory. It turns out our memories are sort of like jello, they take time to.and while they are setting , its possible to make them stronger or weaker. It all depends on the stress hormone-adrenalin.The man who discovered this is James McGaugh, a professor of neurobiology at the University of Ca

9、lifornia, Irvine. McGaugh studies memory in rats, and he invited us to watch the making of a rat memory. In this case, how a rat whos never been in this tank of water before learns how to find a clear plastic platform just below the surface.Well, hell swim around, randomly, and he does not.Can he no

10、t see the platform?No, he cant see the platform. His eyes are on the top of his head.The rat will swim around the edge for a long time, until eventually, he ventures out, and by chance bumps into the platform. The next day, hell find the platform a little bit faster. But watch this rat, who learnt w

11、here the platform was yesterday, then received a shot of adrenalin immediately afterward.Notice it starts out not on the edge.Wow!There you go!Oh! Thats impressive.Adrenalin actually made this rats brain remember better, and McGaugh believes the same thing happens in people.Suppose I said to you: Yo

12、u know, Ive, Ive watched your programs a lot over the years. And although it pains me that I have to tell you this I think you are one of the worst people Ive ever seen on.(Ha ha.) And dont take it, dont take it personally.So my stress system would go into overdrive, no question.Even, even with my t

13、elling you that its not true. There is nothing to keep you from blushing, from feeling warm all over.I am warm all over.Yeah!I am, no joke. Really.Thats your adrenalin. And I dare say that you are going to remember my having said that long after youve forgotten the other details of our discussion he
