While cleaning the bedroom up a bit, I opened the blind to the windows there to discover that the entire frame at the base of the windows on the left-hand side was moldy. Will have to do something about this soonest...but, I wonder if that's why I've been feeling somewhat ill of late? Here I was thinking I had caught a bug or some such or had my allergies going full tilt (which it could be, since I have an allergy to molds and the like)...
Anyway, got to take care of this soon.
