Looking for an (apparently) surefire way to trigger all your latent/not so latent repetitive stress injuries? Here you go.
Day 1: do yoga, including one downward dog pose (as in, put most your body's weight on your hands and bent wrists) and a few triangle poses.
Day 2: do yoga again, including one downward dog and a few modified cobra poses. Continue to do lots of dishes, yank at your sourdough starter, browse the internet, type a little, then manhandle two of the giant (3' by 2', maybe), badly made plywood drawers in your kitchen which are currently full of your heaviest pots and pans. Don't think, "Hmm, maybe I shouldn't pull on this so hard; maybe I shouldn't lift this entire plywood box of a drawer full of heavy things out." Instead, think, "It is so important that I do this right now! So important! Keep going." Reach in an odd way with your left arm. Trigger giant throbbing pain shooting out of your neck, into your shoulder, down your bicep, and down your forearm. Try again with your right arm, because you are that dumb. Trigger pain again in right arm. Breathe through it, try again, reach and fix the thing you wanted to fix, then lift the drawer back into the slot mostly with your knees (it was a weird maneuver). Collapse a bit, realize you are now in great pain in both arms. Realize the pain is getting worse.
Make a brief list of the things you can do without using your arms. Jump into a hot bath with epsom salts. Watch Project Runway. Vow to not be so dumb. Stop typing.
