The lingering cough turned out to be pneumonia, aka "old man's friend" because while the coughing is tedious the anoxia produces a dreamy lassitude.... Better to treat it, though, unless you're ready to go.
@rpardee Thanks, but it's nowhere near that bad--my O² sats are in the mid-90s.
@ImagineThat good show. Would it make sense to lay in some oxygen too?
