When do you get to the point where you say, “Oh shit, I’m getting old!”? I mean, not the facetious attention grabbing commentary that some (like myself) have been guilty of running since the ’90’s. No, I mean the knowing deep down, the kind where maybe you don’t utter the statement so flippantly. I know now it happens during times like when you realize you don’t know what came after “Generation X”; or maybe when you reflect back that those grey hairs of yours now have a history of their own. As if the grey hairs themselves are getting old and looking back. OK I’ve got it, it’s when you start doing relativistic math, like “from the ’30’s to the ’70’s is like from the ’70s to the ’10s” and then kind of shudder at the ability to remember entire eras. Or how about this, when the people you knew start dying.
