Minor ailment!

It is the inevitable consequence of international travel during the teaching semester, I fear: I could tell on the plane on the way home on Sunday that I was having to make an effort to breathe through nose rather than mouth so that I wouldn't be overwhelmed by dry airplane air, that is the giveaway. Not a bad cold on Davidsonian scale (3 out of 10, maybe?) but will have to give it some days off from exercise so that I don't turn minor into major ailment. Ugh! A bit grumpy, though feeling ill enough that I cannot say I have an urge to exercise. Slept for twelve hours last night and will do the same again tonight if it is physiologically possible!
