It’s a little after 9am, and I have now completed everything: got this week’s lab set up, got tomorrow’s lecture prepped, finished a really cool book, and now the day yawns open before me, with lovely blue skies and -20°C temperatures. I think that means I can go take a walk. Get some exercise. Pick up some groceries. Breathe a little bit.

Only a little bit, though, because the student homework starts streaming into my computer by midnight.

Maybe I’ll tell you about the book later. Walk first.
