Despite my best effort, today's (pi day) walk did not involve 3.1415... Granted it wasn't much of an effort. The usual 15.1 km averaging 9:15 per km. A little more exercise at 111 bpm (moderately moderate 74%). 7.2C with 79% humidity.
I might have some pie. What does the rest of the world, that writes dates in a rational way, do today?
