Hearsay With Cathy Lewis

What is it that truly worries you? Why do some risks feel more frightening than others? In a day where worries and risks include climate change, cancer concerns, and a war on terrorism, how do we decide what risks are actually dangerous and which ones are false alarms? On this encore edition of HearSay, Cathy talks with David Ropeik, author of "How Risky Is It, Really? Why Our Fears Don't Always Match the Facts," about finding a comfortable place between fear and fact.
