Bill Radke speaks with University of British Columbia professor B. Brett Finlay about his book, "Let Them Eat Dirt." Finlay's research shows that parents don't need to fear germs as much as they do. Finlay says bubble wrapping kids to keep them clean denies them many good microbes that help keep them healthy.
