Aha!  So that’s it.  Tomorrow I’m taking all the doors out of my house.
Ever walk into a room with some purpose in  mind, only to completely forget

what that purpose  was?

Turns out, doors themselves are to blame  for these strange memory lapses.

Psychologists at the University of Notre  Dame have 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.
So it’s not  aging, it’s the darn door!
Thank goodness for scientific studies like  this!
