Sometimes my knee’s a bit twingy. One good part of my job is that I can sit or I can stand. I can walk around the classroom. I have a lot of physical freedom depending upon how I script the day’s activities. Teaching works well for people who don’t like to sit. I’m probably a better teacher for my restlessness, too. Even as I try to keep students seated, I am able to feel compassion for those who struggle to stay with the program. I try to work breaks into the routine that let students get up and move around a little.
