Some foggy thoughts. To me it's all contingent on whether your brain is healthy, functioning properly, ideally at an optimum. People who talk of Life Extension say that improving 'healthspan' and lifespan are connected. Probably society needs a range of brain ages to function, or has done until now at least. That said there is no possible utility to people getting degenerative brain disease, I don't see the point of keeping the vehicle if the driver is dead. Also consider the tasks a person does in life. A blue collar man dies much younger than rich woman, I think 20-30+ years. Some of that may be avoidable through better healthcare or technology or simply unavoidable because of genetics but it's also hard to imagine intense physical labour doesn't affect your metabolism in such a way that it ends your life sooner. As a blue collar worker I'm becoming aware of this drawback..! On the other side I know workers who've worked physically demanding jobs who are in their 90s and are still trotting about, have full head of dark hair.
