“I would rather questions that cannot be answered than answers that cannot be questioned.” Richard Feynman – Nobel prize for physics.

My prior question – apparently arterioles do get atherosclerosis.

Did my “interval day” today: 1.58 miles – 22:18 with 6 intervals. Pretty dispiriting. I could feel my feel hitting almost heel first. Years of effort, I did fix on the “intervals.” Is it my Z_Sandals? Will use another pair of shoes next time.

My resting heart rate generally stays around 50 (according to my watch). Couple of weeks ago there were several days at 49 and one at 48. Today for the first time since July 4, it is 49 again.
