Freedom degrees. Roughly -13° or 38° if you live in the sane parts of the world.
I’d pick triple digits, mostly because I’ve lived in places that routinely hit 100° in the summer, and I hate shoveling snow.
Speaking from personal experience, 9F won’t kill you, at least not quickly, and it’s pretty easy to put on enough clothes that you can spend entire work days outside being comfortably warm. I used to work outdoors regularly in Alaskan winters and except for days where it got down to around -20F I was usually able to keep warm just by having proper attire.
You can’t really do that at 100F. Sure, it probably won’t kill you if you stay hydrated, but it will never be comfortable.
