Why no gardening? All that need to bend over and twist?How about container gardening? And raised bed gardening? I use a wheelchair and can't get down on my hands and knees to garden, but I have a little herb/flower patch planted in a half whiskey barrel, so the earth is the same height as my lap, more or less. Basically the same phyisical requirements as houseplants, but outdoors, in the sunlight, fresh breezes, and all that jazz.
Geez, Louise! if the docs ban gardening all together, their out of their gourd! ;-)
