Interesting thought. I was raised in a small town in northern NJ, no farms, no factories, heck not even a traffice light in town. Gee I miss it. I was told by my Dr. {many years ago, so I am sure this has changed} that the only link between MGers was an abusive childhood and or an alchoholic parent. I didn't and still don't see how that could cause MG so I never put much stock into what he said.
