I pay attention to fit Professors more I noticed this the other day. Now, at my university I am very lucky the have mostly thin professors who are all really great at their job. However, in one of my classes, both the professors are fat. I had a hard time paying attention in this class and I thought it was the material. On Monday we had a guest Professor who was probably early 40s, grey hair that was shaved, and very fit. I'm sure he was a runner or cyclist. Anyway, I paid attention the whole class and even talked some. I realized that the class if very interested but I just can't pay attention to fat people. Looking back on all my most "boring" classes, the professor was fat and I didn't pay attention. I think my brain was telling me, "don't listen to this person, they don't know what they're talking about."
