The site ReadWriteWeb has an interesting piece on smiling and life satisfaction.
“Researchers J. Patrick Seder and Shigehiro Oishi at the University of Virginia in Charlottesville discovered that smile intensity from a single Facebook profile photo in the first semester of college predicted self-reported life satisfaction three and a half years later, at the time of college graduation.
“This type of study isn’t actually unique to Facebook, however. A 2011 study by Harker and Keltner showed that female students smiling in their college graduation yearbook photos from 1958 and 1960 were reportedly happier 30 years later. A similar study by Abel and Kruger (2010) found that professional baseball players who smiled more intensely in archival photos lived seven years longer than those who didn’t smile much.” Read more.
I hope you’re smiling.
