My first semester of teaching came and went and I survived. I actually really enjoyed it - especially my undergraduate students. I was prepared for a hellacious time, being so busy that I couldn't even eat or shower, so the fact that my semester was a few notches below that was a pleasant surprise.
The other big news is that I joined a gym and TD and I are working out together. We did this pretty regularly his first semester at Harvard, but I literally hadn't darkened the door of a gym in over 2 years (and I hadn't done any other exercise either). The big moment for me came when I basically couldn't carry our canoe back up from the river (never mind lift it onto the roof of the car).
I've been pretty successful at getting into a regular workout routine (for the first time ever?) - we go to the gym together 3 mornings a week & I do 20 minutes of cardio & then lift weights. I am doing 20 or 30 minutes of yoga a few nights a week. I also have been running and I am happy that I can run 30 minutes without stopping (or feeling like I am dying). New shoes help too.
