Thanks for the info Corney. of course, this sort of thing is unnecessary, if only the G.B. would have some New Light on Blood Transfusions.
The JW Doctrine on Blood is thoroughly discredited anyway, the "Scriptural" argument having been demolished by people who actually know how to read and understand the Bible. The G.B. know this, hence their trying to reverse out of the harshness of their application of the Doctrine by bringing in the laughable Blood Fractions teaching.
They could not totally do a 360 turn on the Blood nonsense, because they would face costly Litigation from families who had lost loved ones unnecessarily. So people still have to die, for something the G.B. could change with the stroke of a pen, oh and some new Light. But as usual with the G.B. $$$$ come first, before lives.
