How to subvert the negative stereotypes about older women? Kim Chakanetsa brings together two women - both in their late 70s - to discuss how to grow older with purpose, passion, and a certain playfulness.

Chilean author Isabel Allende is one of the most acclaimed writers in the world. Her novels, which draw on her own eventful life, tell stories of love, exile and loss, and have sold more than 70 million copies and have been translated from Spanish into 42 languages. Now aged 76, she has spoken openly about how to live passionately at any age.

Also aged 76, Lynne Segal is a British-based feminist academic who has grappled with the paradoxes, struggles and advantages of ageing in her book, 'Out of Time: The Pleasures and Perils of Ageing'. Originally from Australia, Lynne is also a seasoned feminist and social activist and is Professor of Psychology and Gender Studies at Birkbeck College, London.
