There&#x27;s no science here about brains if you were looking for some, as I was. The relevant part of the article (and aren&#x27;t they always?) is in the last paragraph:<p>&quot;We so often follow the lefts and rights that the GPS lady tells us without thinking about where we’re going,&quot; he says. &quot;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.&quot;<p>I actually agree with this but it appears to me as if the man is saying, &quot;stop buying maps on your phone and start buying my maps instead&quot;.<p>He should be saying &quot;make your own maps of your place and here&#x27;s how&quot;.
