"I have received letters from young people who say they are contemplating suicide. I've received a few from mothers who say they're planning to kill their children and themselves," David Morrison, a NASA scientist who answers letters from the public, said.

"One touching letter (said) simply, 'My best friend is my little dog, please tell me when I should put her to sleep so she won't suffer in the apocalypse,'" he recalled.
