Yes, I have a brief comment.
As I think my colleagues have indicated, it is extremely important to find the cause for any disease. For Parkinson's, for example, substantial evidence links Parkinson's with pesticides, metals, and other things.
The challenge is can you remove all the pollution, and at what cost? I think the solution would be to find the highest-risk population and intervene a little earlier, but not on a large scale that causes unnecessary economic burden. When it's something where we know the cost.... Take pesticides, for example. You can't ban pesticides. Some of the farmers use certain things, and they don't want to grow less food.
So you really need to support research in that area: how to prevent disease, on the one hand, and on the other, how to balance the other costs to society.
