This mentality of theirs is what really gets me, they are the first to squeal about how we can't tell anything about their health by looking at them and that we aren't a doctor so why should they listen to us anyway, then turn around and take medical advise regarding their weight from bloggers and models.  Also in general the mentality that if you aren't X then you can't possibly know or comment about subject X is so obesely childish. Yea, I am not an electrician therefore there is no possible way I could know anything about electricity. I am not a chef therefore there is no possible way I know how to cook. I am not a nascar driver so I can't possibly know anything about driving.  Some people like educating themselves about as many subjects they can possibly find but I understand completely how this is a foreign concept to them. Probably because I educated myself about it.
