Absentmindedness or Is It Something Else?

In my office environment, we have a little kitchenette that houses, among other things, a photocopier, a refrigerator, a microwave, a sink, a dishwasher, cubbies for mail sorting, recycling bins, and drawers for office supplies.  The photocopier is a network printer, and is positioned adjacent to the refrigerator.  Sometimes, when I would print a document and walk over to the kitchenette to retrieve it, instead of going to the printer, I would open the refrigerator and be temporarily confused as to why I’d opened it.  A few nanoseconds later, I would then remember that I’d actually printed something and should therefore have gone to the printer instead.  I realized I was doing this several months ago, and have consciously tried to curb it.

Yesterday, I printed something and, instead of going to the printer, I walked over to the microwave, pressed the button to open its door, and was momentarily confused as to why there was nothing in there.  As usual, it took only a few nanoseconds for me to realize that I was supposed to have gone to the printer.

Am I losing my mind or do I just have a subconscious predilection to food?  I hope it’s the latter, brought on by the recent change in my diet (which lead to weight loss).  But, if that’s so, is my subconscious potentially losing that battle?  Am I inadvertently gearing myself up to straying from my healthy eating habits?

What if it’s the former?  What if this absentmindedness is a sign of something infinitely worse?  I believe myself to be quite detail-oriented, and attribute my success at work to it.  Is immersing myself in too much work-related details causing me to lose my grasp on the simpler tasks?
