Physical Death

Physical death is the permanent cessation of the biological functions that define a living organism. This occurs when the body begins to shut down and is no longer capable of sustaining life. Physical death is ultimately an unavoidable, unifying experience that symbolizes the end of life and is recognized as a central part of human identity and culture. It is frequently accompanied by legal and religious rituals that provide structure and meaning to our lives. Physical death has profound implications for individual, societal, and global well-being and is a source of much scientific research. An understanding of physical death is essential for research, healthcare, and policy decisions related to end of life care, health disparities, and mortality prevention.
