*These cartoon books are my opinion and are based on my own observation, current research and my own theories. Consult a doctor before taking actions based on the data in these books. They are as accurate as I have been able to make them. If you have research that corrects or improves them, please forward it to me, so I may keep these books current.

I encourage you to read these, read up on the subjects more, observe what you see in real life and make your own decisions.
