Wii-strain yourself
The possible health drawbacks of owning a wii are pointed out above… I mean, it’s all a bit obvious, though, isn’t it? The risks are exactly the same as playing any exertive sport, plus a few from playing any console game on a TV.
Also, the article doesn’t seem to understand the difference between the Wii, and Wii sports, the free game that comes with the wii.
Still, it’s probably important to do more warm-up and stretching exercises. Personally, I’d see this as an opportunity if I worked in Nintendo: a warm-up channel would be a pretty simple addition to download to the wii itself, and a great PR exercise.
