Physical Danger
Did we mention that water polo is one of the most brutal sports in the world?
Kicking, punching, clawing, and scratching—and that's just for starters. Try getting kicked in the throat a few times, or caught in a chokehold under water. We said it before and we'll say it again—this is not a sport for those afraid of bruises.
Then again, what contact team sport isn't without a little danger? Doesn't that make it all the more exciting? You do have good health insurance, don't you?
