This must be pretty obvious (perhaps my smart-watch is spying on me). I've started getting lots of ads for "Chair Yoga" to help seniors lose wait and stay fit.

Mark has apparently been reading over my shoulder. He's helping me do the chair exercises by knocking pens and pencils off my work desk, forcing me to lean over double to retrieve them. As soon as I put the pen back on the desk, he knocks it back onto the floor.

After about twenty minutes of bend and stretch exercises, he decides I've done enough to remain healthy enough to feed him and empty his box, and I'm allowed to get back to work while he takes a quick nap to recover from his share of the exercise.
