FFR too stimulating?

[VegetaRobGT]

I started playing FFR just recently- since I havn't played a lot since I started nearly five years ago- and realized that I didn't really even play that much then (or seriously for that matter most of my games consisted of insisting a perfect game or tapping the arrows furiously to lose and start over.) So I started playing - and I got into it, and after I did- I was awake for five days straight. And I've never been awake for such a period in my life before- I took a break deciding not to play really late last night and finally got some sleep. But just wondering- when you are trying to break the barrier between how fast you react with hand-eye coordination like that... how many people have died from playing FFR?
