Ahh the been there got the t-shirt fact! I wouldn’t know as when we all go on winter sport we snowboard and ski, we do not spend all our time in the hospital looking up nationalities as you seem to do. But everyone needs a hobby. So far not known anyone to come back injured so maybe it’s not as bad as you think, seeing as you also thought there are no hills here.
My wife's Dutch, I know loads of Dutch people who have been or go skiing. I know two people who have injured themselves skiing (dislocated shoulder / broken hip) - both English.
So yeah, I'm with you here, don't think it's true.
