I apologize if this has been covered already, I haven't read all the posts in this thread...

Am I the only one who is watching Water Polo for the first time and thinking it's one of the most brutal sports ever? It doesn't seem so at first appearance, but it gives me anxiety just thinking about those guys treading water and swimming nonstop for that long and that actively, plus all the below-the-water blows/grabs/whatever... and nothing but a silly headpiece on and a speedo.
