I love exercise.

I spent all morning studying physics. I got through the first physics lesson. I plan to do all the practice tests for it this afternoon and evening. I couldn't even look at another note, though, before I went out for a run. Nothing too long. But I feel so much better just having gotten out of the house for a little while. I am stimulated! Now I've gotta get through the first of the tests before I go to CrossFit at 5:30. I hope the rains holds off so I can bike there.
