It’s easier for the human face to smile than frown. It takes twice as many muscles to frown as it does to smile. Moreover, we do not have to “learn” to do it. Although babies imitate the facial expressions they see, smiling isn’t just learned by imitation. Children born blind never see anybody smile, but they show the same kinds of smiles under the same situations as sighted people.
Smiling is of great help to us. Some studies suggest that the act of shaping our mouths into a smile (creating a “physical smile”) can help us see the brighter, funnier side of things. People wearing the physical smile tend to feel happier. In addition, smiles signal to others that we are people who might be nice to talk to and work with—and that can help us make friends.
Unfortunately, sometimes you may find it difficult to smile. Anything from getting a bad grade on a test to losing an important game can make you feel sad. In such hard times, there seems to be no reason to smile. But there is some good part to almost every bad thing. Turning something that seems all bad into something good is one way to help you smile. Hanging around people who are positive and in good moods is another way to help you find your smile again.
