Sheer laziness has probably been responsible for more shortcuts, not to mention valuable inventions, than we are ready to admit. Most of us are continually on the lookout, at least subconsciously, for easier ways to perform onerous or routine tasks.

The old mountaineer continued to gaze into the fire for a second, sighed, then said, “Aw, Ma, why dont we just call in the dog and see if hes wet.”
