what is connected sticks. you remember one thing because it connects to something else you know and you forget another as it's not connected. or much more likely: it is actually in your memory (ie neutral pathways that 'represent' that item exist, but you have no way of actively or consciously recalling it as you cannot find those pathways in your own mind. all that works by association, so connection is key - and then you need strong connection and repeated use to make sure it's not overwritten (the connections get weaker as each neuron makes new or uses other connections) and continues to be connected.
