To get a sense of what this means for your cognition, imagine a studio apartment. There is only one room. Every time you want to use the room, you have to completely change out the furniture. Want to sleep? Set up a bed and nightstand. Want to host a party? Take down the bedroom and set up couches and coffee tables. Need to cook? Drag that all away and set up a stove, counter, and cooking supplies. Sound exhausting? It is! And it’s the same for your cognition, when you switch from task to task.
