About
Death is the end of an organism's life. It is the irreversible cessation of biological functions that sustain a living organism. Death is inevitable for all living things, as nature's tendency to disorder will cause all living systems to degrade and fail through various causes. The identification of the moment of death presents certain difficulties. A person may experience clinical death that is reversible, resulting in some cases in a near-death experience. Some organisms, such as the immortal jellyfish, are biologically immortal; however, they can still die from causes other than the effects of aging. While death as an inevitable end state may be achieved through aging, death can occur at any stage of human development, including in infancy. In humans, establishing death of the brain is the most certain metric for evaluating whether an individual has died.
