Sun Moon / Library of Congress Rehab hospitals see the unlucky and the lucky. I shared a room with a woman who went into her office on a weekend. Thieves broke in. They stole laptops and beat her over her head. Because it was the weekend, no one found her until Monday, when she was in a coma.

Three months later, she suddenly woke up. That's when I met her.  She was in a wheelchair and was terribly skinny -- less than 100 pounds. She ate lots of candy to fatten herself up. She did not seem angry.
