well my theory on the matter is sumthing along the lines of, if all humans could do it, itd become so common that it wouldnt seem weird...like touching urself...everyone can, so everyone does... and nuthing seems weird if ur used to it...like sneezing...think aobut how fucked up sneezing is...yet everyone goes on as if nuthing ever happened...argh! theyre following me again...woohoo! ally mcbeals on!
