It was IBM's binary to character transform. DB2 can still use it if you configure it to do so. Or was at least as of the version from 1998 that I had to replace.
I sincerely hope that if they come up with a 128bit instruction set they call it "x80" to maintain backwards compatibility with previous set names and be deliberately confusing to everyone.
Because your body can (and sometimes does) overshoot the mark and kill things it isn't intending to kill with heat. It also uses up your stored energy meaning you must eat more and more often.
Better to make your body stop overheating itself, and trap heat with coverings. If you get too hot, it can be modulated by reducing or adding cover. And external heat like a water bottle can bring temps up quickly, and keep you at raised temps safely.
There is also the discomfort from a fever as well. Too much discomfort will lead people to make possibly bad decisions. Pain management is always something to keep in mind.
While the understanding would be nice to have, I suspect it is more a lack of backbone than anything else.
