Book cover for Ken Jennings' book "Because I Said So."
We've all heard warning like, "Don't go swimming for an hour after you eat!" "Never run with scissors," and "Chew on your pencil and you'll get lead poisoning," from our parents and teachers.
Chances are if you're a parent, you've said some of those things yourself, but are they true?
Ken Jennings, the man known for his record-breaking appearance on Jeopardy, wanted to fact check these parental gems.
Jennings joins the show to talk about his new book, "Because I Said So: The Truth Behind The Myths, Tales and Warnings Every Generation Ppasses Down To Its Kids."
