Ron Gutman: The hidden power of smiling英语演讲稿带中文翻译：When I was a child, I always wanted to be a superhero. I wanted to save theworld and then make everyone happy. But I knew that I’d need superpowers to makemy dreams come true. So I used to embark on these imaginary journeys to findintergalactic objects from planet Krypton, which was a lot of fun, but didn’tget much result. When I grew up, and realized that science-fiction was not agood source for superpowers, I decided instead to embark on a journey of realscience, to find a more usefultruth.我童年时，一直想成为一位超级英雄，我想拯救世界，让每个人都快乐，但我知道需要超能力才能让我的梦想成真，所以我展开这些想象之旅，到克利普顿星(超人的家乡)寻找星际间的天体。
这很有趣，但没什么成果。
当我长大后，了解到科幻小说不是超能力的好来源，我决定展开一场真正的科学之旅，寻找更有用的真理。
I started my journey in California with a UC Berkley 30-year longitudinalstudy that examined the photos of students in an old yearbook and tried tomeasure their success and well-being throughout their life. By measuring theirstudent smiles, researchers were able to predict how fulfilling and long-lastinga subject’s marriage will be, how well she would score on standardized tests ofwell-being and how inspiring she would be to others. In another yearbook, Istumbled upon Barry Obama’s picture. When I first saw his picture, I thoughtthat these superpowers came from his super collar. But now I know it was all inhissmile.我的旅程开始于加州，以柏克莱大学从事30年期的纵贯研究，研究一本旧年鉴中的学生照片，试着衡量他们一生的成就和幸福。
藉由衡量学生的微笑，研究人员能够预测研究对象的婚姻是否圆满及长久，他在标准化幸福评量中能得到多少分，以及他能为别人带来多少启发。
在另一本年鉴中，我偶然发现了欧巴马的照片，当我第一次看到他的照片时，我认为这些超能力来自于他的超大衣领，但现在我知道这全来自于他的笑容。
Another aha! moment came from a 2010 Wayne State University research projectthat looked into pre-1950s baseball cards of Major League players. Theresearchers found that the span of a players smile could actually predict thespan of his life. Players who didn’t smile in their pictures lived an average ofonly 72.9 years, where players with beaming smiles lived an average of almost 80years.另一个啊哈!时刻，来自2010年Wayne州立大学的研究项目，观察50年代前职棒大联盟球员的棒球卡，研究人员发现，球员微笑的宽度事实上可以预测他寿命的长度，相片中没有笑容的球员，平均寿命仅72.9岁，拥有灿烂笑容的球员，平均寿命将近80岁。
(Laughter)(笑声)The good news is that we’re actually born smiling. Using 3D ultrasoundtechnology, we can now see that developing babies appear to smile, even in thewomb. When they’re born, babies continue to smile -- initially, mostly in theirsleep. And even blind babies smile to the sound of the human voice. Smiling isone of the most basic, biologically-uniform expressions of all humans.In studies conducted in Papua New Guinea, Paul Ekman, the world’s mostrenowned researcher on facial expressions, found that even members of the Foretribe, who were completely disconnected from Western culture, and also known fortheir unusual cannibalism rituals, attributed smiles to descriptions ofsituations the same way you and I would. So from Papau New Guinea to Hollywoodall the way to modern art in Beijing, we smile often, and you smile to expressjoy and satisfaction.在巴布亚新几内亚进行的研究中，PaulEkman，世界上最知名的脸部表情研究者发现，即使是Fore部落中的成员，他们完全与西方文化隔绝，也因他们不寻常的吃人仪式而众所皆知，他们就像你我一样，也会在某些情况下微笑。
因此，从巴布亚新几内亚到好莱坞，一直到北京的现代艺术，我们经常微笑着。
你用微笑来表达喜悦和满足。
How many people here in this room smile more than 20 times per day? Raiseyour hand if you do. Oh, wow. Outside of this room, more than a third of ussmile more than 20 times per day, whereas less than 14 percent of us smile lessthan five. In fact, those with the most amazing superpowers are actuallychildren who smile as many as 400 times per day.在这房间里，有多少人每天微笑超过20次?如果有的话请举起手。
哦，哇!在这个房间外，超过三分之一的人每天微笑超过20次，不到14%的人每天微笑少于5次。
事实上，拥有最惊人超能力的是孩童，他们每天微笑多达400次。
Have you ever wondered why being around children who smile so frequentlymakes you smile very often? A recent study at Uppsala University in Sweden foundthat it’s very difficult to frown when looking at someone who smiles. You ask,why? Because smiling is evolutionarily contagious, and it suppresses the controlwe usually have on our facial muscles. Mimicking a smile and experiencing itphysically help us understand whether our smile is fake or real, so we canunderstand the emotional state of the smiler.你有没有想过，为什么身处在经常微笑的孩子身边，也会让你经常微笑?最近在瑞典Uppsala大学的一项研究发现，当看着正在微笑的人时是很难皱眉的。
你会问为什么?因为微笑具有演化上的感染性，它能抑制我们平时对脸部肌肉的控制，模仿一个微笑并实际体验它，帮助我们了解我们的微笑是假是真，因此我们可以了解微笑者的情绪状态。
In a recent mimicking study at the University of Clermont-Ferrand in France,subjects were asked to determine whether a smile was real or fake while holdinga pencil in their mouth to repress smiling muscles. Without the pencil, subjectswere excellent judges, But with the pencil in their mouth, when they could notmimic the smile they saw, their judgment was impaired.最近在法国Clermont-Ferrand大学的一次模仿研究中，要求测试对象在口中含住一支铅笔抑制微笑肌肉时，判断一个微笑是真是假。
