Gale Encyclopedia of Medicine (2008) says: Death is defined as the cessation of all vital functions of the body including the heartbeat, brain activity (including the brain stem), and breathing. Death comes in many forms, whether it be expected after a diagnosis of terminal illness or an unexpected accident or medical condition. When a terminal illness is diagnosed, a person, family, friends, and physicians are all able to prepare for the impending death. A terminally ill individual goes through several levels of emotional acceptance while in the process of dying. First, there is denial and isolation. This is followed by anger and resentment. Thirdly, a person tries to escape the inevitable. With the realization that death is eminent, most people suffer from depression. Lastly, the reality of death is realized and accepted.
