Time marches on.  Yesterday, I was in a local urgent care clinic.  My problem was a thumb and tendon. I'm with splint now and in "watch" mode for several days to see how time and immobilization improves the situation.  My best learning about time travel came not from my predicament but from overhearing an older couple with health professionals in a nearby room.  She was in breathing distress, but okay.  She was the patient, sort of, trying to get her story out.  Her husband talked mostly about his problems, not hers.  Comical and yet in time, say, 20 years from now, I can hear myself doing the same.  What else did I learn?  You can travel in time by paying attention to now.
