I agree, we learn a lot more on our own sometimes then from the docs. I am reading a book called the AutoImmune Epidemic. In it, the author discusses how AI problems have risen drastically with the advent of modernization and the increase of chemicals and pollutants in the air. What she says in the book makes a lot of sense to me. I personally think, and mind you that you should not take this as expert testamonial as I am neither scientist nor doctor, that the author of that book may be right. Basically, she says that one way that some people end up with AI is that their bodies continue to buildup the chemicals and pollutants from their environment. Those of us that are already predisposed either genetically or biologically to an AI condition are at higher risk when being exposed to these chemicals and pollutants to reaching our "breaking point" of health. According to her research, the final trigger could be something as simple as an everyday exposure (like car exhaust) or something more out of the ordinary like introduction to a new chemical or pollutant (such as house fire or even vaccine).
