I always figured that I had attention deficit as I would go to the bedroom to get something just to discover that I could not remember why I was there. I sometimes thought, “I am losing it” but now I can blame it on the door. A University of Notre Dame study discovered that passing through a doorway triggers an “event boundary” in the mind that separates one set of thoughts and memories from another. So my brain separates the thoughts I had in one room and prepares a “blank slate” for the next location.
I think this makes a lot of sense as we tend to compartmentalize things in our world and in our head. The door as a metaphor is powerful. We view doors that open for us and doors that shut as beginnings and endings. It is a transition from inside to outside, a new chapter, or one life to the next. Anyway, I am happy to have a reason (excuse) for my forgetfulness.
