The ability to chunk ideas together into coherent chunks is good for long term memory. Different parts of our brain remember different aspects, so you might have had an experience where you heard a song and the song brought back a bunch of memories. And if i m et a conference or some for some reason, I mot n azume, and your name's not there, and i want to remember your name, then then i can use something like a memory palace. So that gives us the common vernacular, like you said, a great example. That is a design patterns longterm memory.
