Sherwood (The Man Who Ate the 747), a writer for the L.A. Times, travels worldwide to gain insight from people who have survived a slew of near fatal phenomena ranging from a mountain lion attack to a Holocaust concentration camp, and interviewing an array of experts to understand the psychology, genetics and jumble of other little things that determines whether we live or die. Readers curious about their own survivor profile can take an Internet test, which is explained in the books later pages. Sherwoods assertion that survival is a way of perceiving the world around you is enlightening, as are some of the facts he uncovers: you have 90 seconds to leave a plane crash before the cabin temperature becomes unbearable; luck has more to do with personal perspective than chance. But Sherwoods balance of self-help, scientific theories and first-rate reporting is diminished by occasionally overwrought prose as well as the countless survivors stories, which can run together in a touchy-feely stream of faith and optimism.
