In research conducted by psychologists, volunteers participated. The researchers asked these volunteers to share 230 photographs, which depicted players of major League baseball USA 1952, according to the degree of openness and the width of the smile. Eventually formed three groups.
In the first group were players who smiled “duty” smile. Second – ironically, precisely in the face of their was a slight hint of a smile. And the third were those who smiled sincerely, “from the heart”.
Those who were in the first group lived an average 75 years. These people smiled “teeth”, not the eyes. That smile-called in honor of the flight attendants of an American company “pan American”.
Members of the second group – the owners of the “hint” to the smiles on average lived less than 73 years.
But those who were in the third group, lived for about 80 years. Sincere and open smile called “Duchenne smile” after the French scientist, first described in detail the physiology of the smile “from the heart”. In this smile involves the entire face.
But such conclusions were not only due to the smile. The fact that scientists have proved that people who are pessimistic attitude towards life are more prone to viral infections, they often have problems with the gastrointestinal tract, and nervous diseases.
But those who are living positively and optimistically, themselves and treated as a result of the positive emotions the body actively produces hormones, that improve the heart, immune system and blood vessels.
