It seems like gardeners find a way to work within their confines. There are blind people who garden and I know a veteran that lost an arm and has trouble with legs that were broken badly and healed. He is a fine gardener. We work at our own pace, on our own schedule and within our own limitations. I developed vertigo last fall and so now I go about falling all over the garden and staggering about like a drunk grasping at whatever/whoever is nearest. I have learned to walk with one hand on a staff (I tell people it is my snake stick) for stability in case the vertigo hits and not to carry precious things in my hands that I will toss trying to catch myself. A wheelbarrow is a good tool for carrying things and also for holding onto. Any living creature is welcome on my lap while I am sitting but I cant carry them anymore. It could be a lot worse. we adapt where we can and keep our sense of humor and spend more time in the garden.
