At the end of 1981, my gastroenterology term had almost finished and my term allocations for 1982 had been chosen. In the midst of all this time consuming and interesting research work I was still a physician in training. I was fitting in the research around education and patient commitments. In the first 6 months of 1982, I was to be a haematology registrar looking after the bone marrow transplant patients. In the second 6 months I was to be the physician at Port Hedland Hospital, a rotation to a point 2,000 kilometres north of Perth which attracted "hardship bonus", . $5,000 extra over 6 months. By then, I was very excited about the spiral bacteria. I had developed a degree of confidence in our methodology, and believed that we could safely carry out a study on 100 or so patients. I was able to keep the work going, continuing the research by fitting it around my other duties.
