Thank you for the links JHK. Insightful.
The biblical prohibition on blood involves eating it.
I wonder how many JW know the analogy between a blood transfusion and a dextrose/feed transfusion is false - a blood transfusion is not food and won't save your life if your're starving, in the same way a kidney transplant wont. A bloodtransfusion is analogous to an organ transplant - something the wtbs used not - and now does - allow.
Food for thought.
