There's no science here about brains if you were looking for some, as I was. The relevant part of the article (and aren't they always?) is in the last paragraph: "We so often follow the lefts and rights that the GPS lady tells us without thinking about where we’re going," he says. "There’s something so alienating about this, like we’re not actually in the space. And it turns out this is a very powerful and absolutely essential part of brains that we’re losing. We need to do something to exercise it, and my maps can be a good place to start." I actually agree with this but it appears to me as if the man is saying, "stop buying maps on your phone and start buying my maps instead". He should be saying "make your own maps of your place and here's how".
