content: From the video creator:  The boys and girls at this time (in US history) didn't exercise together...that didn't come in this school until the late 70's.  The girls did more typical PE. What is interesting to look at (which I'll be able to show in the full documentary film) is footage shot the same day of the girl's PE and the boy's PE.  The girl's were doing a "sports-based" PE similar to what exists today, and the boys were focused on a fitness-based program.
