If you haven't heard of Eben Alexander's book "Proof of Heaven" which is #1 NEW YORK TIMES BEST SELLER list for many months now you might want to give it a read. Many have criticized him for the level of scientific research in the book which amounted to this:  
"While the neurons of my cortex were stunned to complete inactivity by the bacteria that had attacked them, my brain-free consciousness journeyed to another, larger dimension of the universe: a dimension I’d never dreamed existed and which the old, pre-coma me would have been more than happy to explain was a simple impossibility."

 I had heard about Alexander's experience long before his book came out and I stated in my book that he would be making a grave mistake to claim the afterlife exists because of his experience. The fact that he is a neurosurgeon doesn't give more credibility to the Near Death Experience that millions have experienced around the world. I noted that his rise to center stage to tell of his experience because of his credentials should have gone instead something like this: "What happened to me was an event that I never imagined could have happened in a diseased/dead brain.  We must put aside our scientific beliefs that consciousness cannot exist outside of the body, which is the status quo position of materialistic science and spend the time and money required to explore the possibility. Currently the exploration is considered 'pseudo-science' and not given the proper time, funding and attention it requires."
So the golden opportunity to move the research forward took a back seat to book sales. So typical, so maddening.
