Has anyone done an orthopedic study on the heavy book bags children have to carry around? I don't know how prevalent this is, provincial as I am, but where I've been for most of my adult life, school children are not provided lockers and have to carry extremely heavy back packs that are heavy even for me. I feel sorry for the little dickenses, I really do. Shouldn't the era of the paperless office be having a trickle down effect - the bookless schoolhouse?
