34-year-old Dianne Grey was a successful doctor in the south of England, but for the last eight months she has been living in Angola, working for an organisation called Doctors Without Frontiers that provides emergency health care in several African countries. Dianne was a GP in Horsham, Surrey. She had a good career ahead of her and a comfortable life, but she brgan to find her job rather boring. She says, "I was treating patients with routine medical problems - colds, sore throats and so on - and I felt a need to do something more important." The organisation she works for has been sending medical teams and equipment to Angola since 1986. Various armies have been fighting each othervin the area for decades, and standards of health care have grown worse and worse. Outside the cities there aren`t enough hospitals, clinics, doctors or nurses,and many diseases have become a major problem. At first Dianne was shocked, but she has been working hard to improve conditions there. During her time in Angola, she has treated thousands of patients and has been training local people as health care workes. "Working here has been a very meaningful experience", she says. "I have never felt so useful before. It`s so great to know that we have been helping people who really need it". She will be leaving Angola next month, but she has already decided to return to Africa as soon as possible.
