People die, they die doing things (sports, exercise, sex, etc) all the time. Sure 40 hours is crazy but no different that other stuff, tragic yes.
I think I may have been in a game with him
I know, I am going to hell...but I got two hand crossbows and some hate to resolve!

I think the difference is that unlike those other activities, people don't do them for 40 hours without any kind of break. Sports has natural breaks built-in, including end-of-game, time to regroup and start next game.
We don't hear of people dying from reading a book ("man, this book is so good, I just don't feel like peeing right now").
I imagine the situation setup is:
player sets up in comfy chair and goes potty first
player plays, gets tired, dozes off, wakes up and resumes play
player isn't moving, doesn't really need to go to bathroom again.
Not consuming many calories, doesn't need to eat or drink/ignores it and is mostly fine
If player does die, other players assume he went AFK and resume their business. If party is large, he is lost among the shuffle of players.
The player is likely suffering from sleep deprivation effects more than hunger or thirst (40 hours is only 2 days), which may make them decide to keep skipping getting up to do anything else. Since the game is mostly mental, physical weariness doesn't really set in or impact participation. Unlike football, where at some point you'd say screw it and lay down on the 40 yard line for a nap.
And as Thunderfoot pointed out, the sitting forever causes blood clots in legs that causes embolisms is your key risk factor.
I'm puzzled as to why the gamers themselves didn't have some breaks built-in. Was EVERYBODY sitting for 40 hours? Was this guy feeling compelled to keep playing, even when everybody else was chiming in "I gotta pee, BRB!" Most people hear that, and think "good idea, me too!"
I suppose game makers could put in a "get up and move" warning when it senses you've been playing the game non-stop for 10 hours. Not entirely their responsibility, but something nice they could do.
I've probably played a game for a 5 hours without a break (as in not getting up from the chair). After that, nature's call does the trick.
Which reminds me of an ancient native american alarm clock. Drink a bunch of water before you go to bed, wake up at 5am with an urgent need to water a tree. The same mechanism should work on gamers. Drink a 2 liter bottle of Mountain Dew. Have to unload it in about 2 hours. Don't cheat like those Vegas Grannies.
