When I was little, I believed that (american) football players' bodies were really shaped as they appear on the field. I never personally saw anyone shaped like that, but I thought that's because only famous people could play football, and I didn't know anyone famous. (I only ever saw football on TV, and I thought only famous people were on TV.) When I was in 2nd grade, my brother was then old enough to play jr. high football--I was surprised to learn about the shoulder and leg pads.
