Well my son builds he has some health issues and it makes him focus and he loves it. He shows his stuff on my you tube channel. Just the other day he did his first wiring on a motor he had glow in his you would not believe. He has been building since he was 5 and hasn`t stop. I know a lot of kids are not interested and I`m proud thta my son is. So any of your parents have a boy with HAAD get them to build a model you see a change in the child I`m not sure if that is how its spell but I`m sure you people would know what I mean.
