Don't be such an idiot SomeGuy. You just had someone explains how it works and you said its not true. Water boarding isn't painful because you get water up your nose. Its painful because the water goes into your lungs.

Have you ever eaten or drink something and it goes down the wrong tube towards your lung instead of your stomach? That would be more like it. If you have you know you start coughing right away and its not at all pleasant. And that is only one thing. Not prolonged exposes for minutes.

What happens if you either actually sucks water into your lungs, which causes extreme pain and cuts off oxygen to your body, even after it is stopped(The waters still in there). Or your air way spasms shuts and cuts off your breathing all together. In this case, you can die or suffer brain damage even after they stop as you can no longer breath.

The lungs can filter smoke to a point, it can not filter water. Your not a fish, people don't have gills. Water is not suppose to go into the lungs. If it does, it cause SERIOUS problems.

As you said, how hard would a person have to struggle to cause broken bones? Very very hard. Which means they must have been in extreme pain to have had struggled that hard. Yet you discount the pain as if it was nothing.

Physical effects can happen much later. Especially if the lungs were damaged during it, it may not be clear right away. And yes it is just like rape. Some people may act just like that, especially after prolonged and constant torture. Some of them never go near water again.
