Thank you for posting this. First, we have lived under a huge flight path for years and have always wondered what havoc that might wreak on people. Second, Dr. Blaylock is not stranger to PD, both of his parents had it, first his dad, then his mom. He is very motivated to find both cause and cure.
Having said that, I wonder that if the chem trails are so damaging, why we don't see clusters of PD (or other diseases) along the flight paths and especially around airports where the planes congregate, take off, and land. I have not researched this but can't help but think if this were the case, we would know. Scientists and researchers have been looking for obvious environmental causes for a long time....I doubt they would have overlooked something like this.
We are the only people in our area that I know of that have PD. Many of our neighbors have been living here decades longer than us and do not have PD, although if the chemtrail composition has changed as the article indicates, that might explain why. Perhaps originally chemtrail were not nearly as harmful as they are now, so 30 or 40 years ago living under them was not a big deal, but now it is. Wonder how one could find out exactly what the exhaust used to be, compared to what it is now?
