Because I Said So! by Ken Jennings, 237 pages

This book explores all those parental platitudes we were told such as "No swimming for 1 hour after eating", "Finish your carrots, they're good for your eyesight", "Apple seeds are poisonous", etc., and etc. Shockingly, a lot of those old wives tales are full of baloney. With sarcasm and humor, this Jeopardy champion explores which are true and which are hooey.
