Is any of it true? If so, how true? Ken Jennings wants to find out if parents always know best. Yes, all those years you were told not to sit too close to the television or swallow your gum or crack your knuckles are called into question by our country’s leading trivia guru. Jennings separates myth from fact to debunk a wide variety of parental edicts: no swimming after meals, sit up straight, don’t talk to strangers, 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 amok. Whether you’re a parent plagued by needless concern or a kid (of any age) looking to say, “I told you so,” this is the anti– helicopter parenting book you’ve been waiting for.
