Some prankster from one of my alma maters just invited me to a group called "Facebook
Over 30!"

Um, no thanks.

To my mind, the only activity apropos for an "over 30" tag is basketball. 
At everything else, I’m better now than I was at 29 (unless you consider my time
in the mile, which is likely remains nine and a half minutes, just like always,
even if there is no evidence that I’m slower than I once was). Hmph.

No need to remind me that "shenanigans" is so rarely uttered by anyone under
30.
