I see you have not experienced -30C going on and and on for weeks on end. I promise you, the little wet chills are better. Especially when its windy, though I imagine you dutch know all about that nastyness.
I’ve experienced -50c where I live, it’s typically only for a few days per winter but those days are absolutely terrible. It literally hurts to breathe when you’re outside and you can feel your nose freezing up, and your eyelashes freeze shut if you blink too long or too much.
Even a quick 5 minute walk is excruciating. It’s always a good reminder of my mortality to be outside in that weather, being locked out of warmth would be a quick death sentence.
