It's not often it gets below -15F.
Moerse!!! 
I'd not be able to cope with that. Our mild winters are getting too cold for me.
If i ever have to skip this continent it will be to where the sun shines year round and people drive on the "correct" side of the road.

It would suck for you until your body adjusted to those temps.
One learns to dress properly for the frigid cold. Layers of silk and polyproplylene, sock liners under wool over sock.
Citizens of the Upper Peninsula are called Yoopers. Yoopers use big scoops to shovel snow off their roofs.

I got stopped by the police in Marquette, Michigan Winter of 2015. It was -15F and the wind chill factor was in the -30sF. Neither cop was wearing a hat or coat

Just their undergarments and turtle neck shirts under their outer cop button up shirts!! I live in South Central Michigan, where it doesn't get that cold in the winter. Yoopers are just used to those temps.
I can't take the cold like a Yooper but I am a polar bear when it comes to heat. I just visited friends in Texas and Louisiana where it was in the 90's Fahrenheit. I couldn't stand it mate, I was miserable for the first 2 weeks I was there. All my friends were laughing at me saying it's just Spring, it's not Summer yet, it hasn't even started to get hot yet

I'm not comfortable in anything hotter than 85F/29C. I'm most comfortable between 65F-75F or 18C-24C.
What kind of temperature range do you experience where you live?
