breathing underwater

this video was extremely uncomfortable to watch. In this video, a man details his journey to breaking the world record for holding his breath underwater. The worst part was when he talked about how he tried to create the illusion of not breathing at first. He tried to swallow some scuba equipment (that was gross) and then he thought he might feed oxygen directly into his arteries (that was gross) and then he wanted to breathe liquid oxygen... it was really hard for me to watch. the second time watching it in class I had to close my eyes and plug my ears and take deep breaths. Also, I don't know if this was just me, but he didn't seem that excited. But maybe that's because I closed my eyes.
