The extreme debilitation of advanced old age and severe illness have plagued human beings whose awareness and self-definition encompass both the idea of death and the "marker events" that signal the dying process. How human beings have dealt with such awareness and experience has varied from epoch to epoch, culture to culture, person to person.
