There are several simple signs that the crud has successfully knocked me on my ass, but the biggest sign of all is that I have been home since Friday night (and as of this writing it is now Tuesday afternoon) and though I have been on the couch most of that time, have I posted here?  No.  I'm just now feeling capable of stringing sentences together with some hope of achieving subject-verb agreement, and if I get wordy, even that's gonna get a bit dicey.
