Clive is joined by Anna who is a local student studying History at A level. The subject is taught in small pieces, about events and people but without embedding a good idea of overall time lines so students often get confused about what came before or after other things. And beyond the "recent" history of the past few millennia it is very difficult to comprehend the scale of time going back many thousands or millions of years. Like when dinosaurs ruled the world. Well that is what Clive thinks. Does Anna agree?
