Life extension is the concept of extending the human lifespan, either through incremental improvements in medicine or through radical increases in maximum lifespan beyond its generally-settled biological limit of around 125 years.[1] This field of study has been explored by numerous researchers and advocates, including "life extensionists", "immortalists", and "longevists" (those who aspire to achieve prolonged lifespans themselves). These researchers and advocates hypothesize that future advancements in tissue rejuvenation, stem cells, regenerative medicine, molecular repair, gene therapy, pharmaceuticals, and organ replacement (such through artificial organs or xenotransplantations) will eventually enable humans to have indefinite lifespans through complete rejuvenation to a state of optimal health and youth (agerasia[2]). The ethical implications of life extension are a subject of discourse among bioethicists.

I hope we don't have radical life extension any time soon. At this point, the only people who would get it are billionaires. Can you think of any billionaires you'd want around any longer than absolutely necessary?
