Kinda worried about reporting this, but I stopped stretching my back almost a week ago and ... there doesn't appear to be anything wrong with my back any more. No pain, no kinks. Yesterday I even did a little yard work with no ill effects.

The girl is very careful. After yesterday's run, she wanted to do less. She also does what she says she will do, six laps and no more. As we approached goal I asked if we were going to do another lap, and she said no. 1.2 miles today, and no more.
