oin Jason Hartman as he and author of "Quirk", Hannah Holmes explore human personality types and how they affect who we become, whether extroverted,
conscientious, agreeable, or even neurotic or obnoxious. Is it possible that our hard-wired brain chemistry can even determine our political opinions and economic views? Learn more about the Five Factors in personality and about Hannah's research atwww.JasonHartman.com. Research has shown that mice have personalities, and somewhere out there, perhaps in your own basement, is a mouse just like you. Hannah Holmes has led an adventurous life since graduating from the University of Southern Maine. She was an editor at the New York-based Garbage Magazine in the late 1980s, after which she returned to Maine to start a freelance writing career. She was a contributor in a variety of magazines.

In the late 1990s, Hannah was recruited by the Discovery Channel Online for an experiment called live internet reporting. This grand experiment led her to distant and uncomfortable parts of the world, from hunting dinosaurs in Mongolia's Gobi desert, to the Montserrat Volcano Observatory, where fine volcanic ash ruined her computer and left her hair like a ball of jute twine. She also piloted the Alvin submarine around "black smokers" a mile and a half under the ocean. It was a glorious era until Discovery.com's plug was pulled. Hannah then went on to author several books, "The Secret Life of Dust," "Suburban Safari: A Year on the Lawn," and her recent book, "Quirk," about the many fascinating personality types.
