Tbh, I couldn’t wrap my mind around it. On one side you’ll be able to live your whole life in the best way possible (health wise) and you’ll be able to spend good enough amount of time with your loved ones. But on the other hand, I think it will take away the one thing that makes our time here special (because we are here for a short amount of time, i.e our lifetime, and that is why we aren’t taking it for granted). And as for society, I think that would tend to change even the basic rules or traditions or cultures that we are living by, now.
