vx, What you said about 300-400 children in grades, with no chronic disease,....it also was only maybe one or two out of a hundred that were even overweight at all. I can remember growing up and NOBODY was even overweight, maybe just one or two students here or there, just a very few students, and come to think of it, I can't even remember more than a handful of ADULTS who were overweight. Everyone was thin back then.
