Aggression

In England there are successful experiments involving the playground. The playground is divided into zones (zoneparc). Aggression involves many aspects, such as unemployment, relationships, communication between parents and boys, television as a role model, community...We should list these, list good practices and let scientists evaluate the measures. I also think assessment of how each child learns may have a profound positive preventive effect. We really need to continue to reform schools into more adaptive places, where children learn basics, e.g. time-management ("be quiet for ten minutes") and sublimation of emotions ("I'm angry, I'm going to make a drawing about it").
