No, but...2 things occur to me as I read through this thread.
1. It might not be a bad idea to keep a stress ball or can of play dough (even one those tiny, party favor cans) on my desk at work for stressful days. Stress balls are easy enough to make, with cornmeal or pretty much anything and two balloons (but these are not for people allergic to latex).
2. I took a training for work on proper lifting techniques. The training really was more about preventing back and other injuries, and proper lifting was just part of this. I learned that whatever my body is repetitively doing, I should to the opposite move a few times every 20 minutes or so. For instance, if my fingers are stretched out over a keyboard, typing, I should stop and clench my fists a few times, clenching being the opposite of stretching. Alternately, if I am knitting, with fingers curled in and tense (sometimes), I should stop and stretch my fingers outward.
No but I've been intending to get one. I've noticed that as I've gotten older my hands feel kind of 'sore' when I stretch all my fingers out or clench them and I believe there is a video of hand exercises.
