Re. drugs - are you including meds, just out of curiosity? Not to dump on anyone who legitimately takes antidepressants for a genuine condition, or a Type 1 (or non-fat Type 2) diabetic who takes insulin, but I always find it pretty astonishing how many people around me seem to be constantly on meds these days, and how large the overlap between obesity and said medication regimens seems to be. Muh condishuns!
