Thank you, Madam Chair.
Thanks to all the witnesses for being here today. I've learned a lot.
I have two sets of questions, so I hope to get through both.
The first is about environmental factors. I know that there is an increased rate of Parkinson's--if that's the right terminology--for people who work with pesticides and herbicides. My uncle has Parkinson's and he was a groundskeeper, so he's very sadly one of those statistics.
Dr. Grimes, are environmental factors something you see with your patients? Is there any kind of tracking system, or is it just informal word-of-mouth: “Yes, a lot of the folks who come in my office had this kind of job, or worked in this kind of world”? What are you seeing with environmental factors?
