...and the stuff that actually/probably "sharpens" the "intellect," which looks like a poem by Mary Leader. I f*ckin' dare you linguist-scientists and men and women of powerful words to read your whole way through that poem without accidentally sharpening your intellect in the process. After you click on that link, you might have to click once more to see the poem.
I'd bet dollars to dimes that looking at sheer and utter nonsense like my "afdjkl1-1..." phrase above doesn't sharpen the intellect much. Then the question is, what is it about Mary Leader's poetry that does sharpen the intellect?
