Why did the man go to Seychelles?

Chris: I’ ve heard that you used to work for the BBC, is that true?
Erwin: Yes, that’s true. I worked as a news journalist for the World Service, specializing in Africa.
Chris: Then how could you turn to become a dive master in Seychelles?
Erwin: As I’ve told you, I worked for the World Service in Africa. That was bow I first had the opportunity to visit the Indian Ocean Islands of Seychelles, Mauritius, Comoros and Madagascar - even though I wash’t a diver then.
Chris: So over time you developed an interest in diving, right?
Erwin: Yes, over a period of years I fell in love with Seychelles and by the time I came to live there I was an obsessive diver.
Chris: Did you leave the BBC after you went to live in the Seychelles?
Erwin: No. Diving became part of the reason I wanted to live there, but officially I was on loan to the Seychelles Broad casting Corporation from the BBC -- helping to train the local radio and TV journalists.
Chris: What prompted you to come back to the UK then?
Erwin: To be frank, I became bored of living on a small island. It was quite a stressful experience in many ways, and the BBC wanted me back.
