Kate Quilton and Dr Javid Abdelmoneim continue their health check of the UK, enlisting 10 volunteers to find out if simple lifestyle changes can help deal with pain. Javid and Kate also investigate how much pain is in the mind, explore the beneficial effects of cold-water swimming, and attempt to answer the age-old argument of who tolerates pain best - men or women. They also meet a Scottish woman who doesn't feel pain due to a genetic mutation.
