Why are physicians generally huge jerks?

Anyway... I don't know how you take temperature of people; but I only care about the last 2 numbers (last unit and a decimal). See, human body is normally at 36-37º. That's healthy temp. if it goes lower than 6, you should put on a coat or something. Also, hypothermia: check your toes. If it's 7.n it requires further checking. If it's 8.n or higher, go to the doctor ASAP. If it is 0.x better call the doctor and an ambulance. Any variation on the initial number doesn't mean crap, because <35 you are already a corpse; >43 you are a freaking mutant. Only the last two numbers are relevant. I don't see the advantage in either.

I assume they were talking more about weather because the need to take the temperature of humans is pretty limited for most everyday use.
