We’ve all heard the warnings from Mom and Dad. Wait an hour after eating before you go swimming or you’ll get a cramp. If you swallow gum, it will sit in your stomach for seven years. Chewing on pencils will give you lead poisoning. In his new book Because I Said So!: The Truth Behind the Myths, Tales & Warnings Every Generation Passes Down to Its Kids, record-breaking Jeopardy! champion Ken Jennings searches for the truth behind the myths that parents tell their children. Using case histories, scientific research, and statistics, Jennings investigates the warnings passed down to us from our parents in a book that both informs and entertains.
Do you really need to wait for your parents to check your Halloween candy for poison or razorblades? Jennings says probably not. You're more likely to have octuplets or die by elephant stampede than you are to eat poisoned Halloween candy. Will you really get arthritis from cracking your knuckles? Knuckle popping may be annoying, but it doesn't cause arthritis. Is chewing ice really bad for your teeth? According to Jennings, yes, it actually is. The cold causes the tooth fibers to contract as you chomp down on the hard ice cube, making you more likely to break or chip a tooth. Because I Said So! is a perfect read for fans of Discovery’s Mythbusters, trivia buffs, and those of us who simply want the right to say “I told you so.”
