Smile Teeth ss.jpgMarch 6, 2010, Greencastle, Ind. — A New Scientist story detailing new research on smiling and longevity, which was conducted at Michigan's Wayne State Universuty, also notes the findings of a DePauw University professor who earlier looked into smiling and divorce.

The Wayne State study finds, "Pro baseball players in the 1950s who genuinely beamed in their official photographs tended to outlive more sullen-looking sportsmen and those who put on fake smiles," reports Ewen Callaway. "Players from the U.S. major league with honest grins lived an average of seven years longer than players who didn't smile for the camera and five years longer than players who smiled unconvincingly."

The article later asks, "Is a smile in a photograph really a good measure of overall happiness? ... Matt Hertenstein, a psychologist at DePauw University in Greencastle, Indiana, Matt Hertenstein Today April2009.jpgadds that smiling in a photo may not simply reflect happiness: people who are conscientious might be more willing to heed a photographer's request to 'say cheese', and conscientiousness has also been linked to longevity. Alternatively, players who smiled could be more sociable than others. 'A long line of work indicates that greater and deeper social networks increase well-being and longevity in life,' he says."
