Nice to know that they come to same conclusions as dr Mew: tongue posture, mouth closed, chewing.

I got my hands on a copy of the book from the publisher. All the information is good, but there's really nothing in it that most people on this forum don't already understand. The "Fixes" portion is focused on making sure that people know what the early symptoms of dystrophy are, and making sure that their kids get early intervention.
I'm going to have to write a review for the publisher, but I've been preoccupied. This is an excellent book for people new to these idea to get a full understanding of the issues and the scope of the problem, but there aren't any solutions presented for adults looking to correct.
Very interesting, thank you very much. He says exactly the same thing as Dr Mew
