I would suggest any PIMOs - fully WOKE JWs make color copies of the new card and make small changes to ALLOW ALL medically necessary procedures. After your family or local elders sign the new "Official" medical directive put it in a drawer and replace it with your new "Altered... "SAVE MY ASS NOW CARD" :).
Keep the original around for elders' schools, visiting Bethel, etc. And for heaven's sake do the same for your kids!!!! Watchtower's official card is simply a "heaven's Gate" Cult suicide pact agreement to prove loyalty.
Even Orthodox Jews who bleed everything dry to eat Kosher, take blood, understanding that Blood REPRESENTS life and that LIFE is what is sacred.
The whole subject of bleeding animals in the Kosher style to eliminate eating all blood was addressed and tossed when the extra labor and costs were calculated at BETHEL in the 70s. Yep, it costs a few cents extra to stay free of blood for Bethelites and the GB so they ignore it, but it's OK for the rank and file and their kids to DIE.
