Everything Is Bad for You is a comprehensive catalog of everything that's bad for you and why, complete with references for supporting documentation. The entries are listed in alphabetical order from Air Conditioning (pollution inside an air-conditioned room is likely to be two to five times as great as in the air outdoors) to Writing (writers have an unusually high risk of dying from pulmonary tuberculosis).
With tongue-in-cheek humor, David French points out that the world of risk has become one in which you are constantly encouraged to be fearful about things that don't much matter, and to remain ignorant of things that do.
