On a side note: Breaks and activity are necessary. And maybe, through developing better ways to develop a strong PFC, which is crucial to a non-violent society. I do believe that compulsory schooling, and increasing rates of schooling, lowered the rates of violence somewhat. I don't have proof for that idea, unfortunately, but it is plausible just from the idea that school builds discipline or strengthens the attention network in the brain, and that this kind of strengthening has been linked to better self control and less aggression.
