What exactly is the moment of death?

Australia-based neurologist Dr. Cameron observes the brain of a woman to know what happened at just 30 seconds before the death. He explained that a person's life can be divided within 10 seconds of just 30 seconds of death. In the upper part of the brain, the characteristics of the human being are stored in the nerves. At first, the nerve cell died. In the first 10 to 20 seconds man's self-esteem, spiritual thoughts die. After this, the nerves of the brain were swollen due to the absence of blood in the brain.
