Because I Said So!: The Truth Behind the Myths, Tales, and Warnings Every Generation Passes Down to Its Kids

Ken Jennings is here to tell us that mother and father didn't always know best. Yes, all those years you were told not to sit too close to the television (you'll go blind!), or swallow your gum (it stays in your stomach for seven years!), or crack your knuckles (arthritis!) are called into question by our country's leading trivia guru.

Jennings separates myth from fact to humorously debunk a wide variety of parental edicts: no swimming after meals, sit up straight, don't talk to strangers, you'll get worms from cookie dough, and so on.

Armed with medical case histories, scientific findings, and even the occasional experiment on himself (or his kids), Jennings exposes countless examples of parental wisdom run amuck. Whether you're a grandparent who perpetrated the myths, a parent who wants to know what you can stop worrying about, or a kid looking to say "I told you so," this is the book you've been waiting for.
