We Should Do Lunch Sometime
Daniel W. Drezner says you should do lunch the right way:

I’ve actually held jobs outside of the academy, and the thing I found most dispiriting about them was the predilection for eating alone at one’s desk, the meal completed in under half an hour. To be sure, sometimes work makes that necessary. However, many people do this out of habit, or to give off the impression that they are such workaholics that they never have time for a real meal.

... Letting one’s mind wander playfully at the noon hour is excellent preparation for the mental rigors that are sure to come in the post-meridian hours. The mind at play is often able to generate the counterintuitive ideas that would never occur otherwise. Nine out of ten of these ideas will turn out to be rubbish, but the ones that stick are special. Many a professor, myself included, will acknowledge that some of their most original ideas came not while staring at a computer monitor or at a blackboard, but while munching on a superior deli sandwich with friendly colleagues.

As one who often eats at my desk while working (or surfing the web or blogging), Drezner's piece made me think. It also made me hungry.
