Did you know that Facebook Addiction Disorder is really a “thing”—and not a FAD? (Sorry, another bad pun—and so soon!) It’s not in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5), but it, and obsessive Internet use in general, is increasingly drawing the attention of psychiatric researchers... None of this may sound very serious, but it’s all tied up with how our brains function. And, not surprisingly, it’s connected to all those other areas of our lives that we know we should better control—such as overeating, smoking, and stressing about things real or imagined. Why, if we’re so smart, and we know what we should do, is it so hard for us to follow through? Are there ways that we can take better control of our lives—without investing a fortune of time, money, and energy?
