Some people say, “But now I have to remember the car, too; you are giving me more to remember.” Not true. With each memory system, you will use something that is already in your memory. In fact, you are simply using all of the otherwise unused space in your long-term memory. You remembered the entire list with ease. Why does this system work so well? If you throw water into a sieve it goes in and straight through. If you line the sieve with a plastic bag, the water gets trapped.
Very true. You are not remembering more by using an analogy as all memories are formulated from pre existing memories, and the synaptic density of neurons means all memories are associative. Very astute observation I think.
