It's wonderful to hear all these brave people talk about how they died and revived, and to hear some scientific, medical and psychological suggestions about how it happens and what changes have taken place in their lives as a result. I hope they do another enquiry where they talk just as openly about what happened within while they were out to it....and have some experienced mystics give their views as well. Brava SBS! Keep the conversations about death going. There is so much to explore.
