I am simultaneously impressed and horrified by people like this.
On one hand, the discipline and determination to pull off something of that magnitude is significant and worthy of admiration. The fact that he could even sleep on a "corkscrew" roller coaster is pretty amazing.
On the other hand, the idea of people going to such great lengths to achieve (and record) such meaningless triumphs is disturbing. Surely that discipline and determination could have been put to better use over the course of a four day period.
I am impressed with his fortitude. I am not awed by his accomplishment.
Roller coasters sure are fun though.
