In prehistoric periods they were freezing to death, homosapiens stalled out and died in Bulgaria in our first attempt to colonize Europe. The only reason that much of Europe is hospitable is because of the Gulf Stream, which I shall note is either at risk for or actively collapsing. I may be from SoCal but that sounds like a rather nice temperature personally, if my balls are outside of my body then it’s too warm, y’all have to be at the edge of frostbite for me to be comfortable.
