As you get older fewer things are surprising. I look at my 90-year-old grandmother and she doesn't seem up to learning things anymore, she's comfortable with what she knows and what she's done in her life. She has no interest in hearing about the internet or computers or anything that's happened in the last 15 years or so.
I find it very exciting to discover something new, it makes me feel alive. Learning tidbits from history -- where the word "bushwhack" comes from, for instance, or what sort of hobbies people had in 1873 -- are good ways of getting that 'zing' of revelation.
Wikipedia is doing away with conundrums and office trivia contests, but here's something that still baffles me:
Sometimes a spider will go on "reconaissance" by dropping from the ceiling on a little self-spun thread. The spider hangs there at the end of the thread, looking around, then climbs back up the thread again, and takes the thread with it somehow.
My question is, what does the spider do with the thread? Does it wind it back up inside its "spinner?" Does it wrap it around its legs? Does it eat it? Does it bite off small pieces as it goes up?
I sent this into "The Straight Dope" a few years ago and they've never answered. Does anybody know? If you were a spider, what would YOU do?
