I found this while doing research. I thought others might might want to read it. You will need a current Adobe Acrobat Reader and if you are using dial up like me it will take some time to load. It is worth the wait in my opinion. It explains the differences between types of diseases, the cause, prevention and treatment of them. It is easier to understand than most of whats out there. It tied a lot of things together for me. Hope you enjoy it.
