For the body:
Thirty minutes on the treadmill, walking at 2.1 miles per hour while watching the PBS show, Origins.
For the mind:
As I noted above, I watched the acclaimed PBS show, Origins, Episode Two: How Life Began. I found it fascinating to learn that we might owe our very existence to a byproduct of bacteria
"...It's amazing to contemplate, but without cyanobacteria, there would be no oxygen and Earth would still be smothered in noxious gases. Plants, animals and humans would have never evolved..."(From Origins: How Life Began.)
For the mind:I only managed ten minutes or so of mindfulness meditation. Partly because of our pets and partly because of an allergy headache.
