Luckily, my parents never treated having children as an impediment to their travelling – in fact we made wonderful wine-mules in the days when there were no liquid restrictions on hand-baggage. Thus since childhood, it has seemed only natural to me that humans would, like many of our fellow animals, be inclined to patterns of migration. Travel throws our senses into a state of disarray, and in all that chaos, there is wonder, there is discomfort, but most importantly for me, there is a sense of being alive.
