Going back to ju-jitsu has been fun. And, if we ignore the usual bruises and one unusual bruise, remarkably pain-free. Yesterday, however, in a display of even more than my usual ineptitude, I pulled a muscle in my upper arm, probably my delt or my pec. Not actually hideously painful, just unspeakably awkward, and, because of the way I sleep, it lead to a lack of sleep and some really wierd dreams.
