托福阅读材料:The hidden power of smiling
0:11
When I was a child, I always wanted to be a superhero. I wanted to save the world and make everyone happy. But I knew that I'd need superpowers to make my dreams come true. So I used to embark on these imaginary journeys to find intergalactic objects from planet Krypton, which was a lot of fun, but didn't yield much result. When I grew up and realized that science fiction was not a good source for superpowers, I decided instead to embark on a journey of real science, to find a more useful truth.

I started my journey in California, with a UC Berkeley 30-year longitudinal study that examined the photos of students in an old yearbook, and tried to measure their success and well-being throughout their life. By measuring the students' smiles, researchers were able to predict how fulfilling and long-lasting a subject's marriage would be,

how well she would score on standardized tests of well-being, and how inspiring she would be to others. In another yearbook, I stumbled upon Barry Obama's picture. When I first saw his picture, I thought that his superpowers came from his super collar.

But now I know it was all in his smile.

Another aha! moment came from a 2010 Wayne State University research project that looked into pre-1950s baseball cards of Major League players. The researchers found that the span of a player's smilecould actually predict the span of his life. Players who didn't smile in their pictures lived an average of only 72.9 years, where players with beaming smiles lived an average of almost 80 years.

The good news is that we're actually born smiling. Using 3D ultrasound technology, we can now see that developing babies appear to smile, even in the womb. When they're born, babies continue to smile -- initially, mostly in their sleep. And even blind babies smile to the sound of the human voice. Smiling is one of the most basic, biologically uniform expressions of all humans.

In studies conducted in Papua New Guinea, Paul Ekman, the world's most renowned researcher on facial expressions, found that even members of the Fore tribe, who were completely disconnected from Western culture, and also known for their unusual cannibalism rituals,

attributed smiles to descriptions of situations the same way you and I would. So from Papua New Guinea to Hollywood all the way to modern art in Beijing, we smile often, and use smiles to express joy and satisfaction.

How many people here in this room smile more than 20 times per day? Raise your hand if you do. Oh, wow. Outside of this room, more than a third of us smile more than 20 times per day, whereas less than 14 percent of us smile less than five. In fact, those with the most amazing superpowers are actually children, who smile as many as 400 times per day.

Have you ever wondered why being around children, who smile so frequently, makes you smile very often? A recent study at Uppsala University in Sweden found that it's very difficult to frown when looking at someone who smiles. You ask why? Because smiling is evolutionarily contagious, and it suppresses the control we usually have on our facial muscles. Mimicking a smile and experiencing it physicallyhelps us understand whether our smile is fake or real, so we can understand the emotional state of the smiler.
