A study by Ernest Abel of Wayne State University in Michigan shows that smile last longer and if the smile is so intense that creates crow’s feet, the better.
“To the extent that the intensity of the smile reflects an underlying emotional disposition, the results of this study are consistent with other studies showing that emotions have a relationship with mental health, physical health and longevity” indicated.
For the study, a team led by Ernest Abel of Wayne State University in Michigan took 230 photographs of players from Major League baseball that started playing before 1950.
The players were classified as ‘no smile’ if looked impassively at the camera, like ‘partial smile’ if your smile involving only the muscles around the mouth, or as a ‘full smile’ if the mouth, eyes and cheeks were involved in gesture.
The photos of the players were taken from the 1952 record of Major League Baseball (USA Championship, MLB), a professional full list of statistics such as birth year, body mass index, marital status and duration of the race, an indicator of fitness. By being as complete statistics, the researchers could verify other factors that could affect longevity.
Of the players who died on 1 June 2009, the category of ‘no smile’ lived an average of 72.9 years, those with ‘partial smile‘ died at age 75, while those of ‘full smile’ lived an average of 79.9 years, according to the study.
Although it is unclear if the players had smiled spontaneously or if their smiles were at the request of photographer, the researchers concluded that even if he smiles at the request, the intensity of the smile reflects the “underlying general provision” of the individual.
