We travellers, we move through so many artificial environments – so many combinations of air pressure, humidity, temperature, gravity – that we forget how achingly good it feels to step into the natural environment your body spent millions of years evolving for. Everything in you settles instantly, as if you are water and the world is the cup. When you look to the horizon, even though you’ve been above it, even though you know better, you can fully believe in the flatness, the endlessness. You wrap yourself in that illusion, and you will never feel safer.’
