Cycling 1:36:00 
Cycling to work, to and from my doctor's office and home again. She has ordered an echocardiogram, an exercise tolerance test and a chest X-ray in order to hopefully rule out the nastier possible scenarios that would explain my chest and back pains plus some blood chemistry analysis on general principle since I haven't had any since 2005 and to help with the ruling out. No order to abandon exercise entirely but not going all out has been prescribed and also avoiding orienteering since the idea of more falls onto my chest seems to alarm her. I guess, since I've paid the unrefundable entry fee and assuming my musculo-skeletal system feels up to it, I'll do the triathlon on Saturday as a tour rather than a race.
I guess I''d better be very careful to at least fall on my butt if I have to fall skiing and skating this weekend - most of the bad things my doctor wants to rule out seem to be possible consequences of shock to various of my internal organs due to falling onto my torso.
Hmmm.... not sure why she didn't ask anything identifiably about my gall bladder. Maybe the blood work will detect some effect of whatever it might be doing or failing to do wrong. Maybe it was ruled out when I didn't scream when she pressed anywhere. I guess it makes sense that since I'm not in much of a position to tell her what my internal organs are up to unless they're sending me pain signals, there's little point asking me anything.
