Recent I had a conversation with an old JW friend. He told me his mother rejected a blood transfusion in a critical fase, and survived it, and of course it's good to hear that she makes it good now.
What me triggered, was a remark he made about what the elder of the hospital committee told him.
This elder praised the mother of my old friend because of rejecting the transfusion. The elder told them that most Jehovah's Witness in the Netherlands take a blood transfusion when their life is at stake. And that here rejection is with that in mind a good and rare example.
So, my observation is that although the doctrine is still there, most witnesses in more "individual" cultures like here in Holland choose to make their own decision.
