I've eaten all kinds of things, including infamous items like balut, dog, stinky tofu, belacan, sheep brain, etc. I'm American and grew up with cheese and love cheese, but after having eaten all of those other things, you realize that the disgust factor of, say, a colorful, pungent chunk of blue cheese is exceptionally high.
