Seem to have some sort of crud. Had it all year, maybe, but it's worse today.
Various sore muscles, headache, sore throat, fatigue. Little bit of fever a couple of days ago; today, slight negative fever, as if my metabolism just isn't getting up to speed.
Doesn't sound a lot like the nasty flu that's going around this year, but I suspect a virus of some sort.
I got out for short-edition morning walkies (having missed Thursday through Monday for various reasons), and a measly little-over-four-miles left my legs very sore indeed.
And there's still work that needs to be done, but trying to get my brain to focus on it is problematic.
