The last stage, old age, challenges the individual to rework the past while remaining involved in the present. The authors begin this work with their theory of life's stages through old age. In Part two, they discuss their interviews with twenty-nine octogenarians, on whom life history data has been collected for over fifty years. Part three is a discussion of the life history of the protagonist in Ingmar Bergman's film Wild Strawberries. In Part four, "Old age in our society", the authors offer suggestions for "vital involvement." Erik H. Erikson is winner of the Pulitzer Prize and the National Book Award.
