One day as my wife and I were walking our two-mile course, I secretly determined to keep up with her--a feat thus far never accomplished. I huffed and puffed most of the way trying to keep pace. I figured that with some effort, I could hold out until we got to her usual slow-down point. When we finally reached it, Deb kept right on walking at the same rate. Breathlessly, I asked, "Honey, aren't you going to slow down like usual?" She cheerfully replied, "Sweetheart, I never sped up!"
