you could always use a bath tub/shower (i am assuming) so long as the temperture of the water is cold enough.
as far as hypothermea (sp?) goes, it is not as easy to die from as most people believe. first off, a good canadian boy like you must have heard of the polar bears.... no not the animal, i understand that our physiology is very different
...... i mean the crazy people that jump in ice cold water in the winter.
i also once saw on the discovery channel a thing on how to survive if you fall through the ice and they said that you could actually last a long time without dying from hypothermia, most people don't die from that, they drownd (sp?). they keep trying to get up, but the ice breaks away until they run out of energy, sink, and die. they explained the special way to get out of the water without breaking the ice, but they said that if you are running out of energy you are best off just to wait for someone to find you. and there have been cases of people that did that and just hung onto the edge of the ice so long that they actually froze to the edge of the ice......
