In Almost Over, F. M. Kamm presents a wide-ranging philosophical discussion of the moral, legal, and medical issues related to aging, dying, and death. She begins by considering different views about whether and why death is bad for the person who dies and what these views imply about the death of humanity. She then considers whether there are conditions under which it might make sense to deliberately bring a person's death about, given the processes of aging and dying that precede it. In the opinion of some it is not only serious illness but ordinary aging that may give rise to this question and Kamm pays particular attention to the various ways in which aging could affect the distribution of "goods" and "bads" in a particular life. Specifically, she considers how the limitations and changes due to aging and the dying process affect meaning in one's life, and whether the absence of meaning affects the reasonableness of not resisting or even seeking one's death.
