A smile is a facial expression that signifies happiness, joy, pleasure and sociability. It is a Universal Language!
According to Primatologist Signe Preuschoft, smiling has gone through a 30 million year evolution!
Although it is seen as a positive thing predominantly around the world, some cultures see smiling as negative and unwelcoming.
In some parts of Asia for example, too much smiling can be viewed as shallow and dishonest or expressed by people who are embarassed or in emotional pain.
