I am very open on the question of the existence of an afterlife, but staying focused on what turned out, on evidence and research or credible assumptions. And not escaping me towards various doctrines relating to spiritualism and practices, reincarnation, beliefs with owning a "astral" body, etc ... the risk of being abused.
Too bad, because the first chapters are serious and include medical, scientific about the coma or the state of clinical death and its definitions constantly changing.
