One of the saddest letters I've gotten from readers was from a woman who had cared for her Parkinson's stricken husband for over a decade. Her whole life revolved around his needs. Eventually, it became too much for her. He froze up when she tried to physically move him. His memory was affected. His sheer size became too much for her. She couldn't handle it, and his needs became too complicated even for in-home help. She had to resign herself to putting him in a nursing home.
