CUT DOWN ON FACEBOOK\nWant to be more content? Lay off Facebook. \n\nIn a study from Denmark’s Happiness Research Institute, 1,095 participants were divided into two groups: one stopped using the social network for one week while the other continued. Afterward, 88% of the nonFacebook group described themselves as “happy” and 84% reportedly appreciated their lives, compared with the Facebook users, at 81% and 75% respectively. What’s more, Facebook abstainers had less trouble concentrating and felt they had a richer social life, but the other group did not report the same change.\nTHE DIGITAL WALKING DEAD\nAn Ipsos survey done for the American Academy of Orthopaedic Surgeons found distracted walking to be a big problem. Seventy-eight percent of those surveyed believe doing something else (such as emailing or texting) while walking is a serious issue. And, study spokesperson Alan Hilibrand says, the dangers are growing: more distracted walkers fall down stairs, trip on curbs or step into traffic. In fact, ER visits for injuries involving pedestrians on cellphones more than doubled from 2004 to 2010, according to a 2013 study in the journal Accident, Analysis & Prevention.
