QR afterward

wow, to sum up the afterward, wow. It's interesting to know that everything I just read didn't just come from a group of doctors or whatever in some far off laboratory doing a bunch of random studies. It's nice to know that this isn't an adult trying to get into a kids head then spitting it out oin paper. This is actually a book where the students helped to write it, or at least gave their input allowing for a better understanding for both the people writing it as well as the people reading it.
