All I Can Say Is "Damn"

I like watching America Ninja Warrior on NBC and all I can say is "Damn" these guys are about the best trained athletes there is.
These guys and some women would put to shame most, if not all, professional athletes, even those who do not complete the course.
I was a pretty good high school athlete and ran a few marathons in my day and I might be able to get through maybe 2-3 obstacles when I was in my prime.
These guys are animals, and in a good sense.
