Ok, so it existed, but to what extent...it sure would be an interesting read! But it would also be interesting to do the math, I wouldn't use data from the 30's or 40's...no, I'd use data from maybe the last 10-20-25 years, and project backwards...I still wonder how prevelant it was...I do think something here recently has triggered it's 'epidemic.'
Ahhh, I think you are touching on the whole Amish theory...but surely there must be other communities too...
lots to ponder!
