post your opinion.

Too much of anything is bad for your health.

"Too much" by definition pretty much means you would be better off with less of something.

It depends on your definition of to much. 12 hours a week? or something off the wall like 40-50 hours.

yeah it depends what too much is, in my opinion if your playing videogames for 6 hours a day (once in awhile wont matter) without a break that could be pretty bad, but 3 hours nonstop wont be doing nothing, lets face it some movies have you sitting down doing nothing but looking at the tv screen for that long. I think aslong as your getting a decent amount of excercise through the day people will be OK. Its just those that sit there for many hours with a 2 litre bottle of cola and eating junk food while doing it are at risk.
