When we travel – to a new and unfamiliar country, for example – many small details become new.

We no longer have any rigid expectations of what to expect from our surroundings, and we are receptive to seeing ordinary things with slightly different features.

We find it fascinating that the buses drive on the other side of the road and are a different colour. We pay abnormally close attention to the dress styles, accents and interactions of locals.

When we travel, we have a heightened awareness of our environment – and we have a greater ‘density of experience‘.
