"If you are building a thirty-story building and you use worm-eaten wood for the frame, inferior structural supports, and other fourth-rate, low-grade materials, what kind of finished product do you think you will wind up with? No need to answer. So if you're building a human body and the material that will become your blood, bones, skin, organs-indeed, every cell of your body-is inferior and of poor quality, what kind of body do you think you will wind up with? No need to answer."
