I hate math, although I'll admit I consider myself to be pretty good at it. You missed the point. We're talking about college and why medical schools require you to do certain things in college curricula. Nobody said anything about life experiences, those are looked at via extracurricular activities, not a transcript. Like I said before, these are general prerequisites, nobody is requiring you to take advanced courses or get a Ph.D. They are requiring you, however, to have at least a general knowledge of things outside of medicine.
Oh and don't worry, the higher ups in charge of these things aren't as dense and narrow minded as you. These "unrelated" requirements aren't going away anytime soon.
