I grew up on the Canadian prairies, where it's a frigid -40*C in the winter (generally for four-five months) and incredibly hot and dry in the summer (something like +30*C and up). Honestly, both extremes suck. That's why I love living on the coast now.
I've endured temperatures of -20 celcius. I didn't find it too bad; after a certain degree under zero, you hardly feel the difference. I'd rather feel numbness because of the cold than complete exhaustion because of the heat.
-20 is nothing, though. As I said, it routinely gets -40*C, which is twice as cold, and trust me, you can feel the difference.
personally if I had to compare 40+ degrees with -40 degrees, at least at -40 I'm not collapsing down on the floor suffering from an apparent heat stroke. at least at -25, you might feel some stinging sensation, but that's way more manageable than 40+
No, you just get frostbite on any exposed skin and can't breathe without it burning. I mean, if the logic is applied the other way, it sounds just as ridiculous, "It was 20*C out here today, and that was fine, so I'm sure 40*C wouldn't be bad".
true, I don't know what it feels like to be in +40 or -40. at most I've experienced +35 and -25. I would still stick with my word and say I'd rather have -25 than +25 (-20 happens on the regular in the colder seasons around here)
Yeah, that makes sense. Take it from me, they both suck. That's why it's best to live somewhere nice and inbetween.
