An independent study of conditions of "clinical death", conducted over several decades, led the American oncologist Geoffrey Long to quite definite conclusions, which he outlined in his book, which is called "Proof of Life After Death". The book describes what happens to people after the pulse stops and the brain stops working. Based on thousands of documentary testimonies of people, he writes the following in this book:
“Looking at the evidence from the research, I came up with nine lines of evidence that I believe support life after death. These lines of evidence follow, each with a short explanation …
1. From a medical point of view, it is inexplicable how it is possible to have highly organized and distinct impressions while unconscious or clinically dead. In our FIPSP study, near-death is the experience of a person who is in such danger that if his physical condition does not improve, death may occur. Those who are near death are usually unconscious and can die from respiratory and cardiac arrest.
To understand how amazing it is that people have a conscious experience during clinical death, it is helpful to understand that when the heart stops, blood immediately stops flowing to the brain. About ten to twenty seconds after blood stops flowing to the brain, the brain activity necessary for consciousness stops. Brain activity can be assessed using an electroencephalogram (EEG), which measures the electrical activity of the brain. When brain activity ceases, the EEG readings turn into a straight line, indicating no measurable electrical activity in the brain.
As a physician, I cannot imagine that any significant experience could happen before death. Can people who are dying be conscious? Doesn't the very term “unconscious” mean that there is no possibility of organized conscious perception? However, although this period should represent a blank slate for the existing CAP, they describe very clear, organized and real experiences. In fact, those with PSP usually say they experienced a higher susceptibility than in ordinary life on earth. It is not medically clear that PSP usually occurs during loss of consciousness.
2. Those who had PSP can see and hear in the out-of-body state, and what they perceive is almost always real. Out-of-body experience (OBE) is the first element of experience for many people with PSP. During PSP, events happen to many that they should not have seen, mainly because these events took place somewhere else, far from their body. These events often include contemplation of one's own unconscious body, as well as furious attempts to reanimate it. The reality of these observations has been confirmed by hundreds of reports.
3. PSP occurs during general anesthesia when no form of consciousness is possible. And this is despite the fact that under general anesthesia there can be no distinct experiences, let alone a greater consciousness than in everyday life. The FIPSP study collected many PSPs that occurred under general anesthesia …
4. PSP occurs in the blind, and this PSP often includes visual impressions. People completely blind from birth in everyday life are completely unable to perceive the visible world in the same way as everyone else. For those who are blind from birth, the ability to see is an abstract concept. They comprehend the world only with the help of hearing, touch, taste and smell. In their dreams, they see nothing, although they can hear and touch. The ability to see cannot be adequately explained to a born blind person by drawing analogies for the other four senses that he has. Although when a blind person has PSP, this experience often involves visual perception.

5. A review of his entire life during PSP accurately reflects the real events of this person's life, even those that he forgot about. Life review includes reviewing important events in the life of the person who had a PSP. One can observe either individual fragments of a person's earthly life, or the viewing can be complete, with a comprehensive overview of most of the previous life …
6. Almost all the people met during the PSP by the time of the PSP had died, and most of them are deceased relatives. When a person with a PSP meets people whom he knew in earthly life, these people are almost always already dead by the time of the PSP. On the contrary, people found in dreams or hallucinations are most often still alive. This is another difference between PSP and dreams and hallucinations, which additionally confirms the reality of PSP.
A person who often has a PSP meets a person who seems familiar, but cannot remember him. Later, the person who had a PSP can recognize this seemingly familiar person, for example, by looking through old family photos.
7. The striking similarity of the content of the PSP in very young children and adults convincingly proves that the content of the PSP is not conditioned by established beliefs. Children - even those younger than six years of age - experience much the same experience during the near-death experience as adults. This in itself is strong evidence that the near-death experience is a reality, not a dream or fiction. Why? Because very young children, unlike adults, almost never heard of near-death experiences. Probably, they do not know anything about watching life events, passing through a tunnel and other elements of the PSP. Usually they first learn about such things when it happens to them.
The fact that near-death experiences are composed of the same elements as adults is one of the most compelling evidences that PSPs are real events and not a product of established beliefs, cultural influences, or previous life experiences.
8. The striking similarity of the PSP around the world suggests that the PSP is a real event. Here's a simple analogy that I like to use to illustrate this statement. If people from the United States, Spain and Mexico come to Paris, will they see the same Eiffel Tower? The answer, of course, is yes. The only difference may lie in the way different cultures describe this attraction. The same is true for people from different cultures who have near-death experiences. Our collection of PSPs from people of different cultures from around the world shows the amazing consistency of all their PSPs.
9. Those who have had a PSP after this incident change in many ways, and often for life. FIPSP studies have found persistent and long-term changes in humans after PSP. Those who have had near-death experiences are less afraid of death, and this is closely related to the increased belief in a posthumous existence. In addition, those who have had a PSP become more loving and compassionate towards other people. Our research has found that those with near-death experiences can choose professions where they need to help or heal people after facing death. Also, many of the studied by us who had PSP changed so much as a result of their experience that they became completely different, better people!
The FIPSP study also found that 45 percent of those surveyed said they had “psychic, paranormal or other unusual abilities that they did not have prior to this event … What interested me most was that some reported unexpected healings. We have seen many such cases in FIPSP studies, including those in which people with very serious illnesses, both physical and mental, are confident that they have healed during or after their PSP.
The transforming property of PSP gives me reason to believe: whatever a person experiences in the next world, some part of this experience remains with him and changes his life in this world."

Such conclusions of the oncologist are based on the analysis of many questionnaire descriptions collected from people who have experienced a state of "clinical death" and deep coma. And in contrast to the unfounded statements of "fighters against pseudoscience", as well as people who believe them with an undeveloped consciousness or a dull mind, they are based on documentary evidence of the existence of consciousness in states "outside the body" and independently of the work of the brain.
