Mariella Frostrup and Dr Mark Porter launch the Memory Experience season with a live programme exploring the life-cycle of memory - from foetal memory to memory in old age. Featuring guests from all walks of life, including novelist Esther Freud and former racing commentator Murray Walker , who talk about their own powers of recall. The programme investigates why teenagers insist on revising with music on, despite parents insisting that the facts won't stick, and asks whether we can exercise our memories in the same way that we exercise our muscles. And Claudia Hammond reports on the biggest ever national experiment on the Subject Of memory. Producers Erika Wright and Nicola Holloway Tips to improve your memory: page 111
