Rubies in Crystal

Running a mild fever, an excruciatingly sore spot in my belly - on my left, lower down, not sure what it could be. Probably they're unrelated: one the flu; the other too much of a work-out last Tuesday doing an abdominals yoga set with my son and then walking a brisk 10km two days later. So Advil and drag myself out to walk the dog in the blizzardy evening, and then rest with a heating pad and perhaps Seven Years in Tibet tonight.
