Serious question - Frostbite

[simplefree]

I don't like the cold and snow and I don't have experience being in places with very low temperature but I was under the impression that frostbites occur on exposed parts of the body?

How did H get frostbitten on his todger?

And what does Frostnipistan even mean? English is not my native language.

@Ridemeginger Those people are seriously tough though. I know someone who did that work and things I would see as needing some treatment, they saw as no big deal. He used to cut holes in the ice with a chainsaw and dive underneath for their work. They talked about tips to find the hole you had cut to get out if you found yourself disorientated.
What Harry had was mild frostbite - frostnip. The person I knew in Antarctica survey would not even have mentioned it.

Exactly, it will have been what was available. I have been there and you do not go there without some decent cream to treat skin.
