I was intrigued about the French mushroom growers in caves who seldom came down with cancer. Also, I wonder if there has been a study of disease and potters who work with clay. I file these little factoids away in my mind.
I googled FR using advanced search, then did a search here on keyword clay. Is this it?
An earlier thread about the French clay
I will try to read more about this as time goes on.
Yes.
Also, apparently folks that worked in the cinnamon factory didn't get the Spanish Flu in 1918.
