Several different things, actually, including the exercises for the arthritis that's developing in my left shoulder, folding laundry, washing clothes, and what I really want to be doing, polishing out the scratches in the blade and properly sharpening my new katana (the Duncan Macleod carbon steel version, if anyone might be interested), but instead, I'm here playing with my old Thinkpad and watching the dog dismantle his latest chew toy.
