I don't get why people are giving the guy a hard time for being sat at a desk for 8 hours. How many of you sit at a desk, behind a pc for 8-10 hours for your job?
Who sit's at their desk @work, for 8 hours solid everyday, without breaks?
I'll reiterate the point as you have clearly missed it - sitting at a desk for hours on end (gaming,working or whatever) is going to give you problems including but not limited to: dizzyness, headaches, poor circulation, muscle aches etc.
Should one be surprised at this? No. The solution? Obvious I would say (and this does not include buying a monitor with a higher resolution).
