Calorie burn from taking about dinosaurs?

Here's an interesting article about linguistics, which says that while some languages are spoken more quickly than others, they all convey information at about the same rate. A little goofy, but the quote below made me think of MFP.

The basic problem of “efficiency,” in linguistics, starts with the trade-off between effort and communication. It takes a certain amount of coordination, and burns a certain number of calories, to make noises come out of your mouth in an intelligible way. And those noises can be more or less informative to a listener, based on how predictable they are. If you and I are discussing dinosaurs, you wouldn’t be surprised to hear me rattle off the names of my favorite species. But if a stranger walks up to you on the street and announces, “Diplodocus!” it’s unexpected. It narrows the scope of possible conversation topics greatly and is therefore highly informative.
