shrimp mashing -- not for the squeamish

Today I learned by clicking through a bunch of things that shrimp have such rudimentary nervous systems that people aren't sure whether or not they feel pain like we do. People have noticed because the way you get shrimp to reproduce in captivity is to squish this one gland they have that inhibits fertilization, and the shrimp don't seem to mind for more than a few minutes. Now I'm glad I pretty much gave up shrimp years ago.

In other news, Tucson is now one of Amazon's same-day delivery zones. Usually nothing particularly useful happens around here unless it's tourist-related, but it looks like Amazon twigged to the fact that Tucson is kind of a spread-out retail desert if you want something Target and Home Depot don't carry. We'll have to see if there is anything I actually need the same day, but it doesn't hurt to have the possibility.
