Question: Why don't they put signs, up high in emergency rooms, so if a patient leaves their body and remembers one of the signs there will be proof of life after death?
Answer: This has already been done. But I don't think the researchers have had any luck with them. Usually when someone goes out-of-body in an emergency room they focus on their body and the things happening around it, not on the room. They may also look for their friends and loved ones.
I wonder why the many accounts already in existence of patients telling about things, they could not have known, and these being verified by Doctors and other healthcare workers is not proof enough. FAQ 05 is a good example of this.
