 What kind of life? It's difficult to say because for senior defectors like Ri, their lives in South Korea vary enormously. At one end of the scale, you've got great success stories like Tae Yong-ho, the former number two in the North Korean embassy in London, who's gone on to a stellar political career. At the other end, you have people who simply fail miserably, who lapse into alcoholism, petty crime and depression.
