I don't think it would be hard at all to prive the Societ's no blood issue. I'm in my mid 50's and I clearly remember it, what about the folks who were in and turned downed blood and or still alive? I'm sure they remember. Better yet ask some Drs, I'm sure they remember their wacky patients saying no blood, I went to a Dr. about two years ago and he was telling me the procedures of some surgery and although he didn't violate the HIPPA law, he randomly worked in something about one of his JW patients totally turning down blood referring to the procedures of the operation or something
One of the wackiest stories I remember is my friends sister who was in labor, she and her husband going to hospital to hospital to explain her situation about blood, one said that she would need it, they both left and drove to another, same story, finally a Dr. who complied with their opinion, but in labor and going from hospital to hspital and still follwing seven old men in Bklyn's rules who have you believing it's straight from Jah, that really sad.
