Last October, Jeanette Mariani was an independent 87-year-old, living alone in Dallas and getting around with a walker. Then one night she switched off the light and tried to make her way into bed. A chair was in the way. And she fell.
"There I was, lying on the floor," she recalled. "I pulled down one of my pillows. I didn't reach very high, just pulled it down, put my head down on it and thought: 'Well, I'll wait until morning.' "
The next day, she called for help.
