Death by Starcraft

It's interesting, the recent news in which a South Korean died after playing Starcraft for 50 hours straight stopping only for toilet breaks.

"We presume the cause of death was heart failure stemming from exhaustion," a Taegu provincial police official told the Reuters news agency.
He was taken to hospital following his collapse, but died shortly after, according to the police. It is not known whether he suffered from any previous health conditions"

But how is it possible to die from exhaustion even if you sit for 50 hours straight, as long as you drink something or stretch along the way. A more probabal event would be a DVT resulting in a Pulmonary Embolus, or even an epileptic seizure with airway compromise. Hmm anyway...better not spend too much time on the laptop!
