Not everyone, but there was usually one far kid in class… my graduating class in 1987 had about 500 kids in it. Maybe 5-10% would be considered overweight or maybe chubby by today’s standards, but the only morbidly obese kid was named Jeff H. At about 6’ tall he was probably 325-350.

Times have sure changed, especially in the big cities. Since we moved to a small town, most of the kids are farm kids and from what I can see are overall much more active and in better shape than the city kids I always saw 4 years ago. More responsible too! Just my observations, YMMV ;-)
