I just came across a great video that explains why smiles are so important. I tried a fun test at my office. I asked my staff to try to frown for as long as they could while I smiled at them. They could not maintain their frowns. This was a fun way to show that smiles are contagious and the more you smile, the more you make people around you happier. Also when observing children, it is true that they do smile often. I have a two year old boy and he is always smiling. His smile lights up a room. Smiles are truly powerful.
