If I eat pretzels, does that really mean I'm a flirt? Dr. Alan Hirsch from the Smell and Taste Treatment and Research Foundation in Chicago says so. He conducts research into a branch of psychology called "hedonics," which deals with pleasant and unpleasant feelings. Hirsch conducted an eight-year study with 800 volunteers and claims the results show that people's snack food preferences reveal their personality type, reports the CBS News "Early Show." (Yes, you may laugh, but Hirsch is serious about this.) He says the link between food preferences and personality is much like a Rorschach ink blot test long used by psychologists for insight into personality. This is the true meaning of all that junk food you eat: - Pretzels mean you're a flirt and you're very lively and energetic. - Cheese curls mean you have great integrity and maintain a high moral ground. - Potato chips mean you are aggressive, a real go-getter who will not take no for an answer. - Tortilla chips mean you're a perfectionist. An "A" is not good enough for you. It has to be an "A+." - Beef jerky means you're the life of the party. You're outgoing and gregarious. How do you rate?
