I am writing this column while sitting in a train – a train that will cover the distance between Malmo, where I live, and Stockholm, the Swedish capital, in approximately four hours. This is a train that runs fast, and I have boarded it after many years, swapping it with the option of taking a flight. A flight would have been faster, even cheaper, but its hyper-efficient process would have robbed me of the opportunity to study the Swedish countryside.
