The game show "Jeopardy" has a category called "Potpourri" that is a catch-all for random answers. This is a Potpourri Post of questions.
1. Because we live in Earthquake Country, Karen and I have an app that alerts us when an earthquake is imminent (based on the fact that sending phone messages at the speed of light is faster than the speed of seismic waves through the Earth). In fact, we were both awakened by an alert at 2:42 a.m. last night.
My question: why is it always the middle of the night? There's no geological explanation, but the odds of me being jolted out of bed by my phone screeching at me like a trumpet of doom are greater than random chance would suggest.
BTW, we never felt the quake, which was a 4.6 some distance away.
2. Karen and I recently took a flight and had trouble getting the "TSA Pre-Check" notation to show up on her boarding pass. After a call to a helpful (really!) TSA representative, we learned that Karen had made a typo in her Known Traveler Number. Once corrected, we had no trouble.
But she'd been using that wrong number for years! Flying all over the place, back and forth across the country, using an incorrect Known Traveler Number that, until now, always granted her access to the Pre-Check line.
My question: how safe should I feel flying our friendly skies knowing that apparently any random combination of letters and numbers has a good chance of speeding you through airport security?
I'll take Potpourri for $600, Alex.
