As extreme cases, quite true perhaps. But these are not real
world cases. In the real world people continue to live in very
frigid climates and in very hot climates. Discussions of
grotesque imposed conditions is really rather pointless. For
instance, I could easily say no one can survive 500C temperatures
and the only response would be, well, yeah, so what?
In the real world roofers in Tucson continue to put tar and
shingles on roofs even in 43C temps and survive to do it another
day.
