I was in London again for a business trip this week. In this day and age, you can travel from Helsinki, have a full day of meetings and be back on the same day.
Even though we may complain about how hard it is to get visas when needed, the amount of security checkpoints and the time it takes to get from one place to another, I am certainly of the opinion that the fact that we can travel over 2000 kilometres and still have a productive day is pretty much a miracle (as tired as it might get you).
