The issue is the online aspect of my job now. When teaching with students, I was up and out of my chair quite a bit. Just walking out between classes, to lunch, or to see other teachers got me moving around more as well. Now I spend most of the day sitting and working on the computer. I'm going to need to do more to combat this extra amount of sitting that I've been doing lately.
My daughter set an alarm to remind her to get up and about every hour or so. I think that I might need to do the same. I need to do more to get my metabolism going and my blood flowing. Unfortunately, there is still a lot to do for my courses (not to mention my doctoral study) that requires me to be in front of my computer.
I'm sure that I'll find a balance.
