Is hypothemia a good way to go...?
No it isn't and it doesn't have anything to do with freezing either, just a cold damp place can cause it.
I have seen this first hand, while guiding a squad of army recruits across the Tors of Dartmoor in UK, hypothermia creeps up on you, rather slowly, like your worst nightmare, it's very cold and you just feel the heat ebbing away from your body, and the person suffering, is not always aware of the dangers, especially if it's wet and windy.
So the next time you go out for a walk, in Europe on a winters day remember, you don't have to freeze, just feel cold and wet, and it will creep up on you!
It's relatively easy to spot the condition if trained for it.
