Here'san interesting one. I attended a special event at Hillsong Church in Cape Town yesterday (I have doubled the speed of the video -- and the sound). At the start, one sees youngsters surging up the steps and into the Church. These are persons 25 years of age and younger. Then I turn my camera around to the right, to film a queue of people who are 26 years of age and older. OBSERVATION: In my "other world" which is rural Africa, it would be quite the other way round. Elders first, youngsters queue.
