LOL, I would bet on there being plenty of what you call math challenged ppl still around or what I call normal people, after all, if people bought things just based on math and ROI the economy of every free country in the world would come to a screeching halt. It would be the end of free enterprise.
Well, I think we've discovered the problem! If those people are what you call "normal", you're most probably one of "them". That makes you retarded, in my professional opinion.
