Why doesn't JK write a physics book for kids to tell them how Harry really does it?

Perhaps Harry Potter could grow up and get a life thus serving as a shining example to those pathetic 'adults' who read a childrens book, getting themselves all het up with excitement over the release of a new one.

Hey Al, perhaps you should lighten up and get a life, Nothing wrong with reading "childrens" books, especially when they have a better plot, and are written better than most of the "adult" tripe out there.

Give it a try, have FUN for once in your life.

I'd like to know why those questions weren't answered in the last book? Seems to me that would have been a more-fitting place to put them...instead of the load of rubbish used as filler.
