But here is a simple truth that many of us seem to resist: living too long is also a loss. It renders many of us, if not disabled, then faltering and declining, a state that may not be worse than death but is nonetheless deprived. It robs us of our creativity and ability to contribute to work, society, the world. It transforms how people experience us, relate to us, and, most important, remember us. We are no longer remembered as vibrant and engaged but as feeble, ineffectual, even pathetic.

By the time I reach 75, I will have lived a complete life. I will have loved and been loved. My children will be grown and in the midst of their own rich lives. I will have seen my grandchildren born and beginning their lives. I will have pursued my life’s projects and made whatever contributions, important or not, I am going to make. And hopefully, I will not have too many mental and physical limitations. Dying at 75 will not be a tragedy. Indeed, I plan to have my memorial service before I die. And I don’t want any crying or wailing, but a warm gathering filled with fun reminiscences, stories of my awkwardness, and celebrations of a good life. After I die, my survivors can have their own memorial service if they want—that is not my business.

Let me be clear about my wish. I’m neither asking for more time than is likely nor foreshortening my life. Today I am, as far as my physician and I know, very healthy, with no chronic illness. I just climbed Kilimanjaro with two of my nephews. So I am not talking about bargaining with God to live to 75 because I have a terminal illness. Nor am I talking about waking up one morning 18 years from now and ending my life through euthanasia or suicide. Since the 1990s, I have actively opposed legalizing euthanasia and physician-assisted suicide. People who want to die in one of these ways tend to suffer not from unremitting pain but from depression, hopelessness, and fear of losing their dignity and control. The people they leave behind inevitably feel they have somehow failed. The answer to these symptoms is not ending a life but getting help. I have long argued that we should focus on giving all terminally ill people a good, compassionate death—not euthanasia or assisted suicide for a tiny minority.
