I would like to see the causes of death of GB members over the years that the rules on blood fractions were relaxed.
they got rid of the ban on vaccinations just before Nathan Homo Knorr set off on his world wide tour ( including 3rd world countries) in 1953. He knew the risk of coming home in a coffin. I bet every relax of the rules relates to the medical condition of a GB who needed it.
i don't have access to death certificates, but I bet there is a correlation!!
