"I used to play for 24 hours straight like you, but then I put a watch on my arm...."
The longest I've ever stayed awake straight was while working on an offshore drilling rig, back in the 70's. We had to work until we'd solved the problems, and it took about 4 days. We took short breaks, but no sleep. When done, we got on a helicopter back to land, and all I remember is climbing into the thing, then halfway waking up when it landed. Got a room slept for a very long time, and woke up starving, then drove back to Houston from southern Louisiana, and ate and slept some more. That sort of broke me for staying awake for long periods, and I've fallen asleep playing Skyrim on more than one occasion. The fact that I'm an old fart helps with that, too.
Old fart has nothing to do with it, been many at time I've seen my brother asleep in his chair in front of his computer with his arms crossed, dead to the world

only thing is I'm evil and from time to time I like to

throw cold water on him to wake him up, needless to say he's all

when he is woken in that matter but it's funny as ol hell
