Chance:
Autism and ADD are NOT man made diseases.
All the medical and psychological research indicates a genetic basis for both.
ADD and Diabetes have something in common. Although both have a genetic basis, their symptoms can be ameliorated through behavioral and environmental factors. Certain diseases involve a genetic proclivity or susceptivity, which in the presence of environmental factor result in the disease. For example, if someone with the genetic predisposition to diabetes ex revises, eats properly and monitors his health, he is unlikely to develop diabetes. Although ADD is genetic, that does not mean that a child or adult for that matter, cannot learn to develop focus.
Further, the idea that autism is caused by vaccinations has been disproven over and over again. Vaccinations have made polio and measles and many other diseases dissappear.
