Personally, I really don't believe in scales or anything like that. You never know when they are acurate or not, and there is already enough pressure in the media to look slim. D< I don't find myself worrying about this sort of thing very often. I'm only 15, I don't want to be constantly worrying about my weight all the time. So, for now, I'm not checking what it is. XD;
I'm 5'7", and I am slim. So wutevr.
