I like how the title of the thread doesn't really have a link to the story.
Does "too active" have a different connotation in Britain?
There is plenty about the headline in the article.
Using the game can also, it appears, have some unhealthy side-effects. As those players who have managed to get hold of it spend more time using the Wii, some are noticing that hours waving the game's controller around can add up to fairly intense exertion  which results in aches, pains and overuse injuries. They are reporting a host of musculo-skeletal complaints including aching backs, sore shoulders and a condition dubbed “Wii elbow†by The Wall Street Journal.
The British Chiropractic Association (BCA) has recently cautioned that Wii injuries are plentiful and says that precautions against them should be taken. “Any unaccustomed exercise or activity lays you bare to problems that could occur from prolonged periods of active movement.
So treat the Wii like a gym workout  warming up and cooling down thoroughly,†says Tim Hutchful, a BCA spokesman. “It is also important to take frequent breaks, which should be every 15 to 30 minutes for those who don't exercise regularly.â€ÂÂ
Some Wii games have pop-up reminders every 15 minutes advising gamers to take a break. Yet research has shown that children play on their Wiis for up to six hours at a time.
