Sherlock Holmes once told Watson that he only had so much room in his "brain" attic and when it's full, for everything added something must go out the other side, and you lose it. That's why he only added necessary information for his work.
Have you ever noticed when you get a song in your head it stays and stays, taking up computing power and distracting you in your "work".
