I am at London-Heathrow airport’s Terminal 1, a little bleary-eyed. It sounds great in theory to have a hotel room to catch a full night’s sleep but then there is jet lag, and rowdy young Icelanders at all hours outside the hotel at a popular all-night hot dog stand. Were they celebrating the winter solstice? I wondered. Or just a Friday night celebration? With the daylight time so short, the distinctions of evening, night time and morning are completely blurred. Even so, I did get a few hours of sleep in a very comfortable bed. Then at 5 am, I went downstairs to check out and get on the bus that picked me up.
