Well, knowledge does not jump from written media to brain, else, everyone would be doing their own molotov cocktail (I still prefer the Joliot-Curie), TNT (pretty easy, we learnt it at school while doing mono nitration of toluene), nuclear bomb ... that is what makes the world quite safe in fact.

I was forced to borrow from the adult library when I was 11 because I had already read everything and I was too demanding. But I guess it was not enough :)

But I don't think hidden social rules are taught in books. Behaving «socially correctly» is not taught either. Which so far has been quite my main problem.
