Ping. This one is truly disturbing.
I really do not see why... Not being a Catholic, I frankly couldn't care less about what the RCC says about this or any other subject... And I will gladly put an addendum in my living will to use this procedure if I am on a ventilator to harvest my organs...
On a humorous side, Any body with a heart and lungs that would fail when the plug is pulled probably doesn't have any organs worth scavengening. The rest of the organs are probably wore out to.
