Same as Phoebe. I put down the similar word, misspelled, at 36, and spelled correctly at 66. By 70 I had figured I had guessed everything around the subject I knew and did a clue-cheat by checking out
this wikipedia article to see if anything jumped out at me, then ping-poinging to the correct answer at 78.
Someday again I'll do it without clues/cheating, maybe a day where I can sit and really think for a few hours. But like yesterday, which once I got to largest city in Nigeria, and my brain went blank, I knew the chances were about even that it'd come to me in about three hours or three months, I figure searching wikipedia for something surrounding that subject instead of taking the loss. Maybe for fairness, I'll cheat / get clues, but not put in the answer once I find it.
Meanwhile, just seconds ago I got an ad on Twitter for "Real Housewives of Lagos" so maybe I'd have figured it out closer to 36 hours.
