Thousands of people have had near-death experiences, but scientists have argued that they are impossible. Dr. Eben Alexander, a highly trained neurosurgeon, was one of those scientists. However, he changed his belief after suffering from what should have been a fatal case of acute rare illness and being in a coma for 7 days. In this book, Alexander relates the details of his experience from the point of view of a neurosurgeon and discusses how this has affected his views on life, philosophy and medicine.
