«I gotta work out. I keep saying it all the time. I keep saying I gotta start working out. It's been about two months since I've worked out. And I just don't have the time. Which uh..is odd. Because I have the time to go out to dinner. And uh..and watch tv. And get a bone density test. And uh.. try to figure out what my phone number spells in words.»

«The University of Nebraska says that elderly people that drink beer or wine at least four times a week have the highest bone density. They need it - they're the ones falling down the most.»

«There is something else which has the power to awaken us to the truth. It is the works of writers of genius. They give us, in the guise of fiction, something equivalent to the actual density of the real, that density which life offers us every day but which we are unable to grasp because we are amusing ourselves with lies.»

«Physicists have determined that even the most solid and heavy mass of matter we see is mostly empty space. But at the submicroscopic level, specks of matter scattered through a vast emptiness have such incredible density and weight, and are linked to one another by such powerful forces, that together they produce all the properties of concrete, cast iron and solid rock. In much the same way, specks of knowledge are scattered through a vast emptiness of ignorance, and everything depends upon how solid the individual specks of knowledge are, and on how powerfully linked and coordinated they are with one another.»
