Hisaho Koseki, 82, barely escaped the tsunami when a neighbor drove her to safety. Now she's at a local evacuation center in Kesennuma, Miyagi prefecture. Her son has offered to take her in, but she doesn't want to burden him. "I have chronic ailments, and I don't know how much longer I'll live. I don't want to die, but in this situation, perhaps it would be better if I did," she says.
