oh, heeeeyy! another funny opportunity you might want to think about.....wheelchairs in the stores (that is, if you have no problems being in a store). really. 7 years ago, i had to have surgery on my knees (many months of recovery and physical therapy, too). i spent the whole summer laid up and lame. but, when i was in stores, i would make full use of their wheelchair and motorized chairs. it was not bad. actually, quite interesting for the mind. if you disagree, that's ok, i was just hoping to relieve your conundrum here. hope things go well for you. take care.
