Low temps. My brain boils in high temps. Heat exhaustion too many times. I’d be dead.

Triple digits.
But I'mma use Kelvin

Single as I would die immediately at 100°C

Single digits. You can always put more layers on but you can't take more off than naked.

I use celsius. Triple digit temperatures would kill me.

But after a quick conversion, still single digit. Its pretty standard winter temperature just a little bit inland from where i live. I like it best between -15 and -5 °C (5 - 23F)

Single digits in C or F triple digits in K

Single digits, you can always put on another layer.

Triple digit heat is miserable.

Single digits, 100%.

Single digits range from -9F to 9F. Triple digits start at 100F, and can go way the fuck up from there. (And with climate change, they will!) Once you start approaching triple digits, you have to worry about humidity, because you can easily hit a combination that's literally too hot to live.

Is -9F unpleasant? Sure. But you can layer clothing, and that will keep you comfortable. Death Valley has hit >130F, and when that happens people die, even if they drink gallons of water and stay in the shade.

Celcius or...?

This is why you can't have rational conversations with Americans.

Single digits. I love shoveling snow, and cold weather makes me feel alive.

I love the cold, I wanna live someplace cold.

I've lived in both extremes and single digits wins every time. I never passed out from the cold, but the heat gets me at least once a year.

What is the humidity level?

Single

Given that the average healthy body temperature is ~98.6⁰ F, and humidity on the Gulf Coast tends to be so high you gotta drink the air, I prefer temperatures 85⁰ or lower.

With high temperatures and high humidity, sweat can't even evaporate, forcing your internal body temperature into unhealthy feverish levels. I'm not a fan of heat exhaustion or heat stroke.

I'm also not a fan of freezing temperatures either, but at least people can dress in layers to keep warm when it's cold.

Never going below 100F? There's not enough electricity to cool the houses. Too hot for crops and livestock.

Never going above 9F? There's not enough fuel to heat those houses. Too cold for crops and livestock.

So I guess we all just die.

Single, that would mean there is a lot of water.

It is very hard to grow food outdoors in either case. Underground the temperature is fairly stable at about 30+°F. If that's allowed, and I can manage how to grow food underground, then from experience I know I can easily survive 9°F and spend a LOT more time outdoors than at 100°F

Triple digits because I don't like anything about winter. The cold makes my body ache and nobody does anything because going outside sucks ass. I think I'd get used to the heat, I can tolerate it fine as is. Room temperature below 25°C/77°F feels freezing cold to me.

If those are the options, I choose death.

Depends. If we're talking 100 degrees and no humidity? I could probably do that. The misery doesn't really set in until 110. 10 minutes outside below freezing feels like knives.

Prepping for that climate change huh?

Probably triple. We frequently hit singles here and all we do is complain about how we wish it was summer. I see people pointing out that 100° can be lethal, but not nearly as lethal as 9°

And on the really hot days (although we never hit 100) we still complain, but always follow it with: at least it's not snowing!

Probably singles. -5° and 5° isn't much of a swing. Don't think I could hang at -425°.

Triple digit temperature, single digit humidity. I like it crispy
