Kirsty Young's castaway this week is the scientist, Professor Dame Nancy Rothwell, who is best known for her work in the field of neuroscience and stroke research. She is now President and Vice-Chancellor of Manchester University.

Could it be that her interest in how we keep the human body alive and functioning began when, aged eight, she contracted primary tuberculosis and was so ill she spent 18 months at home?

She says, "Like most academics my fate was sealed during my PhD, I fell in love with research and vowed I would do it until retirement. I was also sure that I would do my utmost to avoid any of those nasty administrative jobs."
