Agony aunt Criselda Kananda found out she was HIV positive 16 years ago and was given two years to live. Determined to change her fate, the South African discovered that most of the information available about the illness was full of stereotypes and judgements. So she made it her mission to help others and became a well-known radio and TV presenter, offering advice on health and well-being. But this is not an easy job. She reveals that in order to cope with other people's pain and emotions she gives herself a 'cry day', followed by 'laughter therapy'.

For almost a decade, the acclaimed Chinese author Xinran Xue hosted a call-in radio show that made her famous in her country. She offered advice to thousands of women on how to cope with traumatic experiences like domestic violence. As an agony aunt Xinran says that her callers inspired her and she learnt from their experiences. However, she became so affected by their stories that she left China in 1997 and settled in London. Since then, Xinran has published seven books, which include some of the issues she heard on her radio programme. In her latest title, Buy Me the Sky, she turns her attention to Chinese children born under the one-child policy, implemented in 1978.
