Degrowth

I'm well aware of what various generations have done to the planet. I'm not sure what that has to do with the fact that the majority of those who get to 60 with their health intact will continue with their health intact long enough to make checking out early kind of pointless for at least a decade, probably two.

My first comment was with respect to whether 60 could reasonably be considered the end of the line. I would argue that even considering planet fuckery, 60 won't be anywhere near the end of an individual life until the environment is damaged beyond all repair. At that point we'll be looking at human extinction, not just personal extinction.
