Ever notice that people respond differently when you smile? Well, research has proven that there is power in the simple smile. Whether it's personal or business — a genuine smile — can bring cohesion and unity. (The operative word there being "genuine.")
For more info, check out this article from the archives of The Guardian Newspaper and this video from the recent TED Talks.
The article discusses recent (from 2011) research about how individuals react to smiling people and how someone's smile influences their perceptions and choices.
