Oppressive heat

It's been around 97 degrees in Seattle lately -- with about the same percentage of humidity. I'm horrible in the heat, barely able to move! I know, I know -- 97 is nothing to complain about, and the rest of the country has it far worse. But I'm hot and cranky and lethargic and I absolutely can't get off my sweaty butt to do anything productive! (OK, I did go to a biz meeting this morning, following it up with a few hours' work... but then I wilted.)
