Thirty years in one job seems unfathomable to most younger people. But for journalists, Dame Jenni Murray and Lucy Kellaway, professional success, a good income and a passion for the work kept them at the BBC and the Financial Times for the majority of their working lives. In this final episode in our series, they open up about their shared experience of saying goodbye to the institutions that defined them, and tell us honestly whether they wish they'd done it sooner. 

Now I'm Grown Up is hosted by Jenni Murray, produced by Antonia Cundy and Theodora Louloudis, and brought to you by Now Teach. The credits for this episode were read by Livvie Podbur.
