Thank you for posting this account. My grandfather had Parkinson's and I have followed news on the disease my entire life. In my grandfather's case he owned a slaughterhouse (in Detroit) and in an accident was hit in the head by a meat hook. I spent twenty years in the fertilizer industry. I always read the chemical sheets on everything we sold. Paraquat which this article mentions was the single most toxic herbicide that we sold. My bosses wife got a small amount mixed with water in her hair once. She grabbed a comb to try and thin the amount. When she stopped combing she examined her comb and it looked like a melted glob of plastic. This shocked all of us and she very quickly went and washed her hair.
