A new book by an intensive care nurse may provide proof of near death experiences or NDEs. Naturally, hardcore skeptics will object that this doesn't meet the criteria of a legitimate scientific study. But at the very least it shows that large numbers of people who have been declared "dead" have come back to report on some amazing experiences. Some of these clearly cannot be explained by conventional laws of science, as when people can describe events that occurred and things people nearby said when they (the patients) were supposedly dead.
