this was amazing to watch. these guys don't just have more skill, better reflexis, and bigger stones than the rest of us mere mortals...they are able to have an epic frighting moment and get past it pretty much immediately. Even when the moment is big enough to actually shake them up (clearly in a couple of these) they forget it and move on. Good lesson there.
