So as we discussed yesterday, you have a bookcase in your room and a bed and that's about it. So you've got books on the shelves and books on the floor and books you shoved under the bed, because fundamentally your brain is a nerd.
And all day long your brain lies on the bed goofing off, and when you need to know something it has to go get a book.
But we don't all have the same size library. So how does the library get built? What makes some people install stacks like the Library of Congress, while others use the free plastic piece of shit they got from the Doctor Suess book club?
Well, that's handled by a very complex process referred to as neuroplasticity, which I will vastly and inappropriately oversimplify here.
