"I had the good fortune to observe a team of two skilled craftsmen drill a well seeking to tap an underground spring sixty feet below ground. Besides the impressive pinpoint accuracy that defined the outcome of their labor, their work could not have occurred without each other. At numerous moments during their three-hour task, four arms, four legs, and two brains needed to operate simultaneously with the risk of serious injury hanging in the balance. Any lapse in their communication would be costly. When it was all said and done, the two craftsmen acted as one."
