An old friend of ours is no longer able to take care of himself, so a friend of his has power of attorney for his care. He needed a walker last year, but because he has Parkinson's, he needed a better quality one in order to get out of his house and get around in his small town. When she tried to get what he really needed, she found that it would take six months to get approval from Medicare for the best model for him (it is sort of the Mercedes-Benz of walkers), so we ended up quietly buying it for him, and told her to tell him that Medicare had paid for it. The only problem is that it is so much sturdier than the cheaper types that it is heavy to collapse and put in the trunk of a car.
