Using “Unused Bandwidth”

Bill Gates believes that the mind has a lot of “unused bandwidth ” that can be filled in while the eyes are just wandering around.

So he had a giant map of the world  pasted on the ceiling of his study, so he could look up at the map whenever he took a break from the computer. He also put up a map of Africa on the wall of his garage so his eyes could sweep over it while getting in and out of his car.

Maps might not be quite our thing,to each their own,but why not surround ourselves with the sort of things we would rather know more of ?Just tap the unused bandwidth?
