I almost never think about Rome out of the blue. When I do think about it, it's because someone or something else brought it up in some way.

Personally I only think about Rome when I see an article mentioning men thinking about Rome.

43% of men thought about Rome in the past 24 hours, there as to be something wrong with this, right? I'm very into Rome and I don't think about it 43% of the days, not even close. I'm guessing there's some selection bias going on in the way these people were sampled.
