@RickiTarr Hi, You have made a good case for length of life but not, I think, living a life of quality or fulfilment. Healthspan not lifespan is a measure that is worth analysing. If a prehistory human died at forty knowing they have served their families and tribe (ancestors and the future) might that be a better life than one lived in despair, out of touch with society and effectively a slave for Google, Meta et all?
