can't be because of that 25 minutes in the "pool" this morning, can it? or maybe the 3-miler I did after work? or because I took my pal Shelly (not that one, a IRL friend and colleague) up on her offer of test-riding her bicycle and went on a 25-minute bike ride afterward?
That might have done it.
That is all. My hotel bed with the too-fluffy pillows is calling my name. g'night.
