And these costs (as well as quality) helped us score each country. We can, however, put a number on the price of medical procedures. Measuring the quality of healthcare is difficult, and it’s hard to put a number on it. In this next stage of your life, you want to ensure you have access to the best care possible, at reasonable prices you can afford. Making the connections between its actors visible may provide a new perspective on social phenomena that occur in this world, including peer review, citation and conference invitations.For many expats, choosing a retirement destination is dependent on the standard of healthcare that country provides-and understandably so. The field of medical education represents what social network analysts term ‘a small world network’. The average shortest path between any two authors in this network was 5.98 (min 1, max 17) the average distance to Lorelei Lingard was 4.17 (min 1, max 10). Co-authorship connected authors into 68 663 unique pairs, of which 61 937 had co-authored only one article 67.43% of all authors were linked to each other through a ‘co-author of a co-author’. The analysis covered 16 653 papers by a total of 24 258 different authors. We further created a website that makes it possible to identify the shortest path from any author in the field to any other, including links to the connecting papers. We found Lorelei Lingard to be one centre of the network of co-authors and determined the numbers of authors who were one, two or more steps away from her. We constructed a mathematical graph from publication data obtained on the top three journals in the field and analysed it using social network analysis methods. In this paper, we investigate how co-authorship connects scholars in medical education and whether the six degrees of separation hypothesis also applies to the network of authors in the field. It is thus hard to imagine how such a highly clustered group could be so well connected to the rest of the world. On a local level, however, many people experience that most of their acquaintances know each other. Conventional wisdom has it that everyone on earth is on average only six steps away from knowing any other person through ‘a friend of a friend’.
