One Circuit Overseer came to visit me when I started to show signs of Apostasy.
I asked him about Watchtower's Ban of Organ Transplants and Vaccinations and the subsequent ban lift in the past. He was staring blankly and with the looks on his face I came to know he genuinely never knew about it or he should have been a great actor.
Such Life threatening teachings of WT, had faded into oblivion within a few decades.
