I have a colleague who calls everyone John - even the females, when he cannot remember names, and he not yet technically a senior. So "senior" moments happen to juniors, too. But it is not just for keeping up the brain cells active; it's a nice distraction when stuck in "macet". I one used some of the questions for a game ala trivial pursuit and it was fun!. My only concern is that a lot of the questions are so Western. Perhaps a localised version can be prepared.
