My thoughts: It’s ridiculous that it took a study to learn this. This is COMMON SENSE. Children have lots of energy. Forcing them to sit still and bottle it up is not healthy. Many kids have been misdiagnosed with ADD or ADHD or ABCD, whatever they are calling it today. Do you not remember being a kid, and being forced to sit still in class. For some of us it was easier than others. But we all would have been better off being able to run around more than sit in a chair listening to monotonous teachers drone on about something they were not passionate about. There may be hope for “education” yet.
