more snapple facts

sooooo today's snapple fact #73 is that the average person will spend the equivalent of 2 weeks over their lifetime waiting for a traffic light to change. How in the world do they calculate that? Is this a worldwide fact or just a US fact? and of course, who really cares? does this mean that there are people who will spend 4 weeks waiting and some that will never wait (those who are blessed with always having green lights)?
