MPTP , DDT, and many other chemicals may be culprits in the well water. pest and weed killers as well as fertilizers may be involved. most farmers are aware that nimal manures and urine are not retained on the surface nor stay in one field. also, most fish have high mercury levels. the point i am trying to make is that the possibilities are somewhat endless. we will die from something or another or a multitude. there is no significant likelihood at present that any of the correlates is going to be proven except for MPTP injections and CO poisoning - and these are not typical PD. (whatever that is.) >> I would just like to help others to become informed so that something good can come from this.<< this is what a lot of us are attempting. until the clues are 'solid', causal factors will remain random chance. feeling emotional need to know a cause or set blame on some thing is not rationally attainable beyond continuing to look for correlations - if you wish to look for a needle in haystacks.
