I have read several book about mediumship, and currently reading surviving Death, Leslie Kean. I also have read time and again the skeptics crow every time they believe they have exposed fraud. The prance and buck at every attempt to make genuine controlled experiments, such as the Swartz experiments. They will never ever be convinced not ever, because for them the brain is the beginning and the end. Hell will freeze over before these critics would ever be anything other than convinced its all smoke, mirror, frauds and deceptions. Wikipedia-Not a good source for a complete treatment or fair treatment of any subject has several long and lengthy treatises discrediting anything suggestive of survival after the brain is dead.
