How does a person feel just before death?

Recently an expert told that what happens before death and how does it feel? According to the report of The Express, a doctor who has seen many people die in his life has told what changes happen in the human body just before death. Scientists also know very little about this. 

The process of dying starts two weeks ago According to the report of Themirror, there are very few studies on natural phenomena. Talking about how it feels before death, a doctor says that the process of dying usually starts about two weeks before the heart stops beating. Seamus Coyle, an Honorary Research Fellow at the University of Liverpool, talks about the process of dying in an article for The Conversation. He said, "I think the process of dying starts two weeks before any person dies. During this time people's health starts getting weak. They also start having trouble walking and sleeping. In the last days of life They also lose their ability to take pills, eat food or drink anything." This happens in the body at the time of death What happens in the body at the time of death is largely unknown, but some research speculates that many chemicals are released from the brain at the time of death, including endorphins. It stimulates the feelings of any person. According to Seamus Coyle, it is difficult to understand the moments of death, but according to the research so far, as people approach death, the the stress chemicals of the body increase. Inflammation also starts in the body of people with cancer and probably others. These are chemicals that increase when the body is fighting a viral infection. In general it seems that during the process of dying people's pain subsides but we do not know why this happens? It may also be related to endorphins. It further said that every person dies in different ways, so it cannot be estimated that who will die peacefully. I have also seen many such young people who had no idea that they were dying.
