The authors attempt to describe the aging process in the context of a continual developmental process from birth to death. They cite some interesting data from the literature and then go on to make some observations of their own. The aging process is described in reference to an individual's life experiences with spouse, children (identification and envy), grandparents and parents (and their death), and others. They refer to these experiences as being involved with extension of the process of separation and individuation (whether this term should be retained only for the early infancy period one must decide for oneself). The authors continually refer to Kohut's developmental theories of narcissism to help explain the aging process.
