Lazy waggling could damage your arm

Reading a New York Times article about repetitive stress injuries caused by the Wii is like taking a little day trip to 2006. In those days, Wii puns had just started to get old, and everyone discovered that repeated activity, even while playing a video game, can sometimes lead to injury.

This particular article features an angle we hadn't heard before: it's actually worse for your arms if you don't swing with the proper zeal. According to the article: "... a flick of the wrist is often enough to return a serve or bowl a strike. As several doctors pointed out, that is the exact motion – concentrating the force of a swing in the muscles of the forearm – that can cause tennis elbow."

Who knew — even as you were committing graphic violence against fake dudes in MadWorld, you were mutilating your own arm?
