The Self-Sustaining Threeble

If an outside intelligence observed the goings-on at my community college over the course of a day, they would likely determine that, based on average intelligence, most humans would not make it to age thirty before expiring of stupidity-related consequences.

If the parking situation is not enough, mull on this for a bit. I saw a man stumble and fall off of the sidewalk while he was texting.

While I waited a half-hour for a parking place, nearly being rammed several times by people who feel they must get the nose of their car into an available parking place before the preceding car is fully out, I played some Brain Age Express: Sudoku while idling in a faculty parking place. (A girl saw me stopped there and gleefully parked beside me before heading into the school. She will have a parking ticket when she comes back out.) As I played, a logical situation that my brain automatically termed the "self-sustaining threeble" presented itself to me in the game. It works like this:

Because the middle row of possible numbers all sort of rely on each other for their eventual existence, the bottom space is clearly available to the missing number eight. I wonder if the Japanese have their own name for it. I also wonder what "sudoku" means in Japanese. I would have just named the game "puzzuru".
