Florence Muchnick, who survived two husbands and retired a millionaire, now shares a single room with a stranger in a south Fort Myers nursing home. It's space enough for two twin-sized beds, the cloth curtain separating them, a television and a small shared wardrobe. Muchnick's family believes she's well-cared-for. But it's a far cry from the luxury condominiums to which the 86-year-old had long been accustomed. Alzheimer's disease has stolen much of her memory of that former life. Medical bills and the astronomical cost of long-term care have taken most of the rest. And beds like this, those set aside for low-income seniors on Medicaid, are in short supply.
