A meaningful life is a construct having to do with the purpose, significance, fulfillment, and satisfaction of life. While specific theories vary, there are two common aspects: a global schema to understand one’s life and the belief that life itself is meaningful. Meaning can be defined as the connection linking two presumably independent entities together ;a meaningful life links the biological reality of life to a symbolic interpretation or meaning.
The National Conference of Commissioners on Uniform State Laws in 1980 formulated the Uniform Determination of Death Act. It states that: “An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem is dead. A determination of death must be made in accordance with accepted medical standards.”So the permanent cessation of all vital bodily functions is known as death.
