xcept for a relative few of us who live near the north or south poles, our perception is that on a daily basis, night falls predictably. For those living in the mid-latitudes of North America, that predictable rate falls somewhere between 700 and 900 miles per hour. While it sounds as if the process occurs at a staggering speed, from personal experience we know the dying light of day lingers for quite some time before total darkness overtakes us.
