Saw the subject brought up on Food Hospital, some time-eater on Cooking Channel. some guy was getting stressed b/c he only wanted to eat local and organic, and, wow, that was not always an option, or, it seemed to me, a truly consistent desire on his part (well, I guess one hamburger won't kill me, he said, or something like that, so, yeah, no it won't...the rest is up to you).
Anyway, apparently we now have another condition with which to be concerned. The more conditions we identify, the more conditions we can cure (or at the very least medicate), and the better the species will evolve going forth.
Right?
