Well, we've all heard stories (and by all, I mean me, because I am God and therefore am everyone) of people playing at an Internet Cafe for an entire night, and dying there. We as gamers scoff, and say "Pah!". But is there truth to it?
Me, I have experienced such a thing. My mind has been week from a day in the sun at the beach, then I come back and play Ratchet and Clank 2 for 4 hours straight. I get an attack of the shivers (in 40 degrees celcius weather) and am sick for a day or two.
Today was the same. After 7 hours in front of a screen (Net Cafe, Movies, TV), I started to feel sick. But on the other hand, last holidays I played 13 hours of Xenogears with no change.
Thoughts?
