Too funny, Sharon! I was just thinking the same thing about the sanitation issue of eating plants from the yard.
Our ancestors were pretty ingenious and you are right, we have lost so much informaton. I have a sister who really appreciates and lives the dream of living off the land. She and her husband love all the old ways and I have learned some things from her. She used to work at the living farm at Lincoln State Park here in Indiana and had to demonstrate how families lived back in the 1800's.
Although you may have sometimes wished for a more luxurious life, you were blessed by the rich experiences and knowledge of those two little old ladies. I bet you could write a book:)
