Spiders and grizzlies and snakes, oh my! Ask someone what they are afraid of, and the answer is likely to be something like a plane crash or shark attack. But the authors of the book “Worried?: Science Investigates Some of Life’s Common Concerns,” Eric Chudler and Lise Johnson explain why they believe we often waste our energy worrying about the wrong things. Chudler, a neuroscientist at the University of Washington and Johnson, an assistant professor of physician assistant studies at Rocky Vista University, say that we feel stressed out about things that are highly unlikely to happen. Instead, we should be more focused on seemingly mundane threats, they explain. Chudler and Johnson talk to us about the risk behind everything from aluminum to red wine, and share ways to take control of the things we fear.
