You've probably heard of Google Glass owners who seemingly can't put the wearable down, but there's now at least one reported instance of genuinely addictive behavior. Doctors at Naval Medical Center San Diego claim that a 31-year-old Navy serviceman is the first person to be diagnosed with a Glass-related internet addiction disorder. The patient wore the head-mounted computer for up to 18 hours a day, and was so attached to it that he would instinctively reach for his right temple (to activate Glass) whenever you asked him a question, whether or not the device was there. He's getting better after having spent 35 days in on-site treatment, according to doctors; that reflexive movement doesn't come up so often, and the man is both less irritable and more focused.
