This is really stupid. Sleep deprivation is VERY unhealthy for your health as the exhaustion also messes with the "running background tasks" of your body, including your heartbeart and other organ functions. A number of young gamers, younger and in better shape than Milkfat, have received heart attacks and indeed died from their all-nighters. It's all fun and games until it happens to you.
Besides, I could have sworn Guiness wouldn't recognize records anymore that involve willful endangerment of the record holder's/challenger's health. As in "the hardest someone could stomp their own nuts", "how long can someone stay up playing HON", et cetera.
