Good for you, Sue! My partner too is an avid gardener, and she too has considerable arthritis. We both find that at day's end if we've not been reasonably active we've both got day's-end arthritis pain. Activity spares us the pain. I keep a copy of choreographer Twyla Tharp's inspiring book Keep It Moving on my kitchen counter, where I can't help but see it 1,000 times each day, purely for git-up-'n'-go motivation.
