Safety first, kids. While that may not be the official motto of Corrupted Saves, it is one that we all like to ignore on a regular basis. But for those of us putting ample time into The Legend of Zelda: Skyward Sword, it may be wise to heed those words of advice. I know we're all so tough that we scoff at those warnings that would tell us that using a bottle of Robitussin to swallow a handful of vicodin right before operating or riding on a mechanical bull while pregnant is a bad idea. But seriously, all that virtual weapon wielding can hurt your wrist.
Motion gaming in general has brought about a whole slew of previously unforeseen gaming-related injuries. Doctors of the past never had to treat Wii Tennis elbow, a Child of Eden seizure, 3DS blindness or Kinectimals rabies. Of course, back then medical "science" said it was ok to remove any afflicted body part with a saw normally used for pruning large trees, and most of those doctors would probably think that video games are a mixture of witchcraft and devil worship. (Well, they are, aren't they?) But that's beside the point.
The point is that all the consoles now carry their own motion magic, and with it, added risk for bodily harm. So for the love of all things holy, be careful.
