Where exactly is the morsel of your brain that reminds you of things, and how does it work? how do you realize you were gonna say something even though you dont know what? how does it suddenly come to you that you had to do something? where is this info stored? is somehow that long-term memory transferred into a short-term memory that triggers you cyclically? is there a little chemical floating around somewhere that periodically bumps into things and causes a reaction, when you go OH YEAH i was gonna say something... the concept is so abstract, and how is it that you remember it even though you can't REMEMBER it? you have no idea what it was you were going to say, only that it was *something*...
