I was buying a new slip on knee brace last week because my knee has been acting up. It dawned on me that we should have crutches and a cane. which we now have. I lectured the wife about how she should have a few pairs of thick sturdy frame glasses cause her "cute" wire frame ones seem to break if you look through them wrong.
All good ideas! We keep a wide variety of ace bandages, self activated hot and cold packs and the canes, crutches and walking sticks. Oh yeah, we also have an old fashioned hot water bottle!
