Because I Said So! is an entertaining look at questionable parental beliefs, and outright old wive's tales, and it's laugh-out-loud funny. Don't be surprised if you find yourself reading half this book aloud to whomever will listen!

In debunking or confirming various pieces of conventional "wisdom," Jennings references a lot of studies and articles, but provides no citations. It's a fun, breezy read, not a research-driven treatise. I found what was true just as surprising as what was not. But the downside is, you may find yourself wanting to know more about a particular study and not knowing where to start.

Good for: Anyone who ever wondered if their face would really get stuck that way.
