Thanks for the warm welcomes.

Yeah, that thing where I decided midlife for me was 26, therefore 52 is death, it was intuitive, with no medical history factored in.  Factors were, like, 1. Age 26 was when I decided that my most meaningful speculations would be upgraded to opinions; I got down off the fence on some topics.  2. And that was the year I first experienced creaky joints, the telltale for: You're not growing up, you're growing old. And I noted some famous counterculture weirdos had died at 52 but I can't remember who they are.  Just recently I heard that 26 is when the brain is considered fully developed.  Hmmm.
