At the end of Expedition Mankind you enter a dark room at the centre of which stands a clock mechanism. It includes small figures that drive the mechanism, turn the cogs, swing the pendulum and create their own time. Time is one of the things that industrialised countries lack most. If we had the freedom to choose, would we spend our time differently? But how free are we? Imagine you were immortal. You want to read a book. But you can also read it tomorrow because you have all the time in the world. But if that is the case, why read it tomorrow? Why not read it in a week, in a year or a thousand years instead? Why should you ever do anything if you can do it all in a thousand years? Maybe it is our limited lifespan that gives special significance to everything we do.
