School was seven hours back in the old days. It’s still seven hours today. If you get detention, it’s eight hours. Of course, back then, we got to go outside for recess once or twice a day. We also had music and art classes that helped get our bodies out of desks. We also knew to behave or the principal would introduce us to the board of education and then it was dad’s belt when he got home.
LOL - that’s pretty much how I got down to 5 hours (recess, lunch, other activities). And yep, unless you plan a career with the WWF, you do have to learn, at some point in your life, how to sit still.
