Probably it's a combination of physiological responses and the algorithmic cleaning up. It's a it's a computational device. At least we see it as a computational device. That's the modern metaphor for how we go in and understand it. And it has to erase stuff. You need a time off. You don't need you can't have information streams processing through when you need to be going I don't not I'm not going to save all that or I'm going to consolidate that and I'm a lot of it's about eraser and homeostasis and recovery. I mean that translates physically into recycling transmitters and rebuilding all that
