Back before chemicals were introduced into just about everything we touch, even books were created from natural ingredients. Although humans didn’t find them edible, there was such a thing as a bookworm that would feed on the fibers of the book and its binding.
As a voracious reader and the parent of two up-and-coming readers, books are a big part of our mental nutrition. We feed our minds on good stories and uplifting non-fiction titles on a daily basis. We visit the library weekly and leave each time with several bags full of books that are completely digested by the next week’s trip.
I’m not sure how the bookworm fared nutritionally, but I know we fare best when we spend our time on books that exercise the mind to stretch itself beyond its normal thinking patterns. New ideas are the mental equivalent of trying new foods.
