Sure you want to know?
Three new books collect what some might consider too much information.
Always Follow the Elephants: More Surprising Facts and Misleading Myths About Our Health and the World We Live In (Times Books) by Anahad O'Connor is a New York Times columnist's look at health facts (yes, you'll get drunker using diet soda as a mixer) and fictions (no, most people don't dream in black and white).
Forbidden Knowledge Travel: 101 Things Not Every Traveler Should Know How to Do (Adams Media) by Michael Powell offers highly irresponsible tips: how to beat a metal detector, sneak into Disney World's tunnels or climb the outside of the Eiffel Tower.
Why Fish Fart and Other Useless or Gross Information About the World (Tarcher Penguin) by Francesca Gould explains such icky phenomena as tarantula omelets, the nosebleed that killed Attila the Hun and the worst job in history (you really may not want to know).
