The refrigerator (/freezer) wasn't holding temperature correctly. You pull out the instructions and the recommendation: clean the grills, clean around the condenser tubes. As soon as the bottom grill came off, the challenge began: find a variation on a twist in Balasana (Child's pose, Wisdom pose), and keep the breath steady. To see what you are doing, place the flashlight "just so". To keep the metal retractable measuring tape steady, I needed patience, endurance and minute controlled movements to catch the balls of lint. We'll see whether the refrigerator has better function after the cleaning.

I know that bringing a technician for cleaning such that I did might have produced a more thorough result -- but it feels good to know that yoga can make such a contribution to everyday life, to being able to look after one's household with more self-reliance.
