This little fellow is focused and feeling no pain.
It is well known your pain will naturally diminish when engaged in a focused activity; that’s hypnosis. Works for painting and sculpting, not so well with housework. This is a good reason your wife should do those mundane tasks. You would, of course, love to do it but you need to ease your pain with some painting. Tell her that her doing the cooking, dishes, laundry, dusting, vacuuming, yard work, auto repairs, etc is the equivalent of giving you a nice massage. Let her know how much you appreciate it and how much it is saving on pain medications.
Oh ya, word of warning, be careful when and how you word this concept. Some unscientific women resist the idea. Probably why I’m on my knees scrubbing the kitchen floor, nursing a throbbing headache.
