What are the vital components of living existence? Certainly there is life; for something to live, it must be born, it must exist in a space of time that is known as “life.” Before and after this period of life is a nothingness known as “death,” the void that contains all that is not life. The structure and definition of death is heavily disputed, but irrelevant to the discussion here. Death is an indefinite, broadly defined concept; life, however, is spoken of much more simply.
