There Are Great Benefits to Keeping a Smile!
People say a smile is contagious. Once you start smiling around someone, he or she just seems to automatically smile too! In physiological terms, a smile is a facial expression formed by flexing the muscles most notably near both ends of the mouth. Speaking subjectively, the smile can be also around the eyes. Smiling is customarily an expression of pleasure, happiness, or amusement. However, it can also be an involuntary expression of anxiety, in which case it can be known as a grimace. There is much evidence that smiling is a normal reaction to certain stimuli and occurs regardless of culture.
