Why Do We Smile?

Everybody likes smiling．But why do we smile？Smiling makes us attractive．We are drawn to people who smile．Smiling changes our mood，as it can trick the body into feeling better．Smiling is infectious．When someone is smiling they lighten up the room，change the moods of others，and make them happier．Smiling relieves stress．It helps to prevent us from looking tired.

Smiling makes us look healthier．It can bring us energy and pleasure．Smiling makes us become successful．Smiling people appear more confident，and are more likely to be approached．Smiling helps us stay positive．When we smile our body is sending the rest of us a message that “Life is good！”

So just try smiling our way through the day．Stay away from depression，stress and worry by smiling．Smile when you meet others．Smile in time of difficulty．Smile when you feel sad．Smile wherever you are and whenever you can．
