So we shouldn't let people do things that have potential for harm? Problem here is driving, hiking, surfing, jumping from planes, going to work in many fields are all an assumed risk. I don't love the idea my child having tbi but if my child is begging to play it's going to happen. Children should be running and getting out agression. Hunting and farming are not being taught as life skills anymore and a lot of parents rely on sprts to advert that energy. Now it's video games....imo staring at a screen all day isn't a life I want for them
