I'm not sure about this article. For as bad as my memory has always been (and especially bad for being a programmer), I don't have many "why am I in here" moments.<p>It does happen occasionally, but as someone who is thinking about "work-on-the-fly" wherever I am, I think I'm just accustomed to noodling over work (or other background processes) "in the background".<p>Since lots of us are engineer-types, are we more apt at that background processing and then when we hit our primary target (in here to look for keys), we're able to shit into primary focus mode?<p>Now if I'm searching for keys, noodling over some design in the background, and then my wife pops me with a question while I'm lumbering through the house, then I'm in trouble;)
