Chris is not a traditional explorer(探险者)- he usually works in an office for a large organization. Yet his job can sometimes be just as exciting and dangerous as being an explorer. Chris works for MSF, an organization also known as Doctors Without Borders (无国界医生). MSF sends trained doctors all over the world to help people after a war or a disaster. Chris is a doctor from France who has travelled to many places to organize programmes that help people.
At the moment, there are over 27,000 trained medical staff(工作人员) taking part in MSF projects and tasks. The organization received the Nobel Peace Prize in 1999. All kinds of doctors can join in MSF. They need to be prepared to go almost anywhere in the world and, of course, they should expect difficult conditions. Doctors with experience in tropical(热带的)diseases are especially useful because most of MSF's work is in Africa. When MSF accepts a doctor for a task, he has to go for at least six months.
But why would a doctor leave a comfortable life and a good salary to join MSF? According to Chris, the experience is a great help in your career(生涯). At the end of each task, you help people in need and have made a real difference to people's lives.
