Water does boil at 80 deg-C... depending on pressure (see its phase diagram). Of course "normal conditions" is the hedge. It's still useful to think about other facets of the "truth." Critical thinking is, indeed, the key.
Where do you expect to find humans at significantly high elevations like say, the peak of Mt Logan, BC, Canada (which is ~6km or 19k ft above sea level, where water does indeed boil at 80 deg C)?
I certainly wouldn't call that normal. Noone lives at those altitudes.
