I taught for years. Can confirm. There also used to just be ONE fat boy and ONE fat girl per grade. Now there are a few of each, and they are already circusfats compared to yesteryear. This is why my extremely "average" (on the medical chart) children look super skinny next to the other kids. Their pediatrician looked like she was going to cry tears of joy the last time I took them in and they were measured and weighed and stuff. She kept exclaiming that they were proportional, like it was something so rare to see.
