BBC producer Felicity Baker has a stammer that she has spent her whole life trying to hide. She struggles to say her own name. Now she is stepping out in front of the camera for the first time to talk about what it is like to live with the condition - and she soon finds she is not alone. She meets a rugby player who blames his stammer for his aggressive behaviour on the pitch, a rapper who found music stopped him stammering and the comedy star Michael Palin, whose father stammered but never ever spoke about it.
