Aging research may significantly lengthen human life spans in the foreseeable future. This paper argues that we do not need to wait until this happens to prepare for the dislocations that may result. Increased longevity over the past century has already raised urgent, unresolved issues of equity, social cohesion, and human dignity. These developments, and our past experiences in dealing with them, provide a basis for revisiting the basic questions raised by all attempts to extend human life: what does life mean, and why is it worth extending?
