Ya, I am sure it varied between school districts. I graduated in the late 90's too. Some schools are worse than others. I agree though, it is a combination of the sedentary lifestyle, larger portion sizes, lack of education (from parents or schools) on how to eat properly, a desire for instant gratification and lack of any self control. I am not blaming the soda / snack machines, I just noticed that they are there and filled with beetus and that wasn't the case when I went to school.
