Great, it reminds me of when I was a kid and played at "space". I used to get a load of old war surplus radios, lots of dials and switches and make consoles. Of course nothing actually worked, this is so much better. Lucky lad.
When I was a kid, I practically LIVED at the Orlando Science Center. They had a space capsule (can't remember which one) and I could lay in that thing for hours running missions in my head. Hadn't thought about that...maybe it is genetic 
"When I was a boy of 14, my father was so ignorant I could hardly stand to have the old man around. But when I got to be 21, I was astonished at how much the old man had learned in seven years."
While I was well aware of the concept, I have never seen it stated so well. I can only hope he feels that way at 21 and I don't have to wait until he is 30
