The Wii's still a popular holiday gift more than two years after its release, but could your coveted console put you in the hospital? Possibly. Apparently, aproximately 10 patients per week are admitted in Britain, after reporting "excruciating pain in the right shoulder or knee," which seems to be caused by the tennis and running games. They're calling it "Wii-itis," and it's worse for those who are double-jointed. The lesson? Stretch before you play.
