With Jane Garvey. How do couples cope when they have mismatched libidos? Australian sex therapist Bettina Arndt has asked men and women to keep sex diaries in order to try and work out how to manage what can become a nightly, arduous negotiation. But is her suggestion that sometimes you simply need to put the 'canoe in the water and just paddle' the way forward? Bettina joins Jane in the studio. It was during the 17th century that Eleanor Glanville became the first English female lepidopterist. At the time, butterfly hunting was seen as a purely masculine pursuit, something no woman in her right mind would ever consider; it could lead to accusations of practicing witchcraft and even necromancy. Jane is joined by Fiona Mountain, the author of a new novel based on Eleanor's life and dangerous obsession with butterflies. Sandra Beale has been practising karate for 18 years and has become the first woman to achieve Shihan - or Master - status in her particular branch of karate, despite repeated and serious bouts of illness. She also specialises in classes for children with autism and Aspergers. She talks to Jane about her karate career and about what makes it such a good sport for children. Is breast best? What, if any, are the health benefits of breastfeeding your child? Jane talks to a leading professor about his twelve year study into the medical impact of breast feeding.
