I think spatially, and so do you. Can you scratch your left ear without looking? Pick a booger out of your nose, without poking your brain? Remember where you left your keys? Can you type, without looking at your keyboard? Know which pocket your phone is in? Which way is up? Do you know where the bathroom is? Of course you do! We imagine multi-dimensional models in our minds, to help understand the complex world around us. We can also leverage this powerful way of thinking, to process more abstract information.
