  1. Close genetic matching, and how to avoid inbreeding: Iceland, a country with a small population, has a phone application which most people, especially young people, have. They use it to track their genealogy, and when they meet a person with whom they may have a relationship, they compare their genealogies and decide on that basis whether they will be meeting for coffees and lunch, or for something potentially deeper.
