My kids have gone back to school and I fully expect my eighth grader to come down with a serious case of scoliosis by the Christmas holidays. I mean, what is up with schools expecting these kids to haul around backpacks that feel as if they are loaded down with about half a dozen bricks? At least if the kids are expected to do this kind of weightlifting all day they could load their lousy school lunches with more carbs and protein.
