Are violent video games bad for kids 12-13 Do they affect behavior

Yes, they do affect behavior. Truthfully I am a kid myself and I know one boy that gets himself into a lot of trouble and most of it is probably from violent video games and bad TV. So if your child is playing violent video games or watching bad TV, make them stop because if we stop putting violence in kids heads they might have better behavior at school and long term, it might help us live it a better nonviolent world. Thank you and please encourage your kids to take the nonviolent route.
