There are three ways to cut something in half: front and back, top and bottom, left and right.
Front and Back
My wrists have been aching. The pain is nothing to be concerned about, only my body occasionally barking at me for years of misuse. Things have improved since taking the usual precautions: slowing down, working less, stretching, taking breaks. I also threw money at pain and bought an ergonomic keyboard and ditched the Apple mouse that gives me claw hand. And, perhaps most importantly, I set up reminders for myself to assume better posture in my chair.
Out of all of these measures, posture is the most pure and difficult challenge. There is no outside influence to help or blame; it boils down to mindfulness and strength.
