For the body:
Thirty minutes walking on the treadmill at 2.1 miles per hour for a total distance of 1.05 miles.
For the mind:
While walking the treadmill noted above, I watched the first episode of Origins on WXXI, my local PBS station. I had no idea how far geology, volcanism and the earth sciences had progressed since my 9th grade science class back in 1965. Terms such as "magma ocean" and "iron catastrophe" and concepts such as the bulk of the earth's oceans being created by the impact of huge, frozen snowballs known as comets helped the 30 minutes on the treadmill go quickly.
For the spirit:
Twenty minutes spent sitting on my upstairs meditation cushion listening to my cat meow up at me.
