This morning Kathy told me that her first-graders are learning about exercise. This is how you explain what exercise is to kids that age: anything that makes you breathe hard, feel hot and turns your face red is exercise.
So then we reflected on a world that requires teachers to introduce the concept of exercise to little kids, who in another day and age would just naturally be outside breathing hard and feeling hot and turning red in the face. Then I remembered how Mrs. Thompson in the fourth grade used to play a record called "Chicken Fat" every day so we could get the wiggles out and also not turn (apparently) into fat chickens. So maybe we weren't really breathing super hard then after all.
A song like that seems kind of p. incorrect right now. But then practically everything we did in my school was p. incorrect. We prayed and the teachers smacked us with rulers. Also paddles. You had to wait until the fifth grade, though, until you got smacked with a paddle.
