Healthspan extension, completeness of life and justice

Recent progress in geroscience holds the promise of significantly slowing down or even reversing ageing and age ‐ related diseases, and thus increasing our healthspans. In this paper, I offer a novel argument in favour of developing such technology and making it unconditionally available to everyone. In particular, I argue that justice requires that each person be provided with sufficient opportunities to have a ‘ complete life ’ , that many people currently lack such opportunities, and that we would substantially improve the status quo by giving them access to anti ‐ ageing technology.
