This came in my email last week and made the facebook rounds, too.
Now it all makes sense:
Ever walk into a room with some purpose in mind, only to forget what that purpose was?
Turns out, doors are to blame for these strange memory lapses.
Psychologists at the University of Notre Dame discovered that passing through a doorway triggers what's known as an "event boundary" in the mind, separating one set of thoughts and memories from the next.
Your brain files away the thoughts you had in the previous room and prepares a blank slate for the new locale.
