I don't know really, because in order to have the "right" answer I guess I'd have to know far more about psychology etc than my own amateur observations. However, I have noticed that involvement in unarmed combat, such as boxing, martial arts etc has turned around lives for some of the young men I've known personally who've been on a one-way trip to a life of fights and prison, and who were destroying their own lives as well as their family's, and their targets. It gives them a healthy way to express aggression and a healthy respect for the art of fighting, IMO. I know opinions do vary widely on that one! So maybe something like that made very widely available, free of charge, perhaps as an optional lesson in schools even, with a choice of other PE type stuff, for the kids who want it? Instead of being, as it is at the moment, an extra only for the parents who can afford it. I suppose, to go out on a limb for a moment, if schools offered options of: combat, team sports, and something like yoga/pilates for the VERY non-physical, non-aggressive kids, no-one would be left out or forced to do something they hated, or were depressingly bad at. And the kind of kids who normally skip PE and/or have health issues would actually have something really light-weight they could enjoy (I speak as someone who was one of those kids!). Also, it has become a cliche but teaching young people how to manage their anger (BAAM do great courses in this, really revelatory on what makes people blow their top) and at the same time having a zero-tolerance policy on bullying in schools....? My POV on things like this is, I don't have to be a plumber to know there's water coming out my ceiling, and likewise I don't have to have the exact answer before I can try to identify the problem - if that makes sense!
