Brian Cox and Robin Ince uncover the unexpected history of the body in the archives of the Royal Society with special guests Prof Helen King, Sir Mark Walport, Keith Moore and Ed Byrne. Together they dissect some of the most surprising and peculiar beliefs that have been held about the body over the last 500 years, from wandering-womb hypotheses to tobacco-enema resuscitations. They unearth how scientific discoveries have often originated from brave individuals, willing to volunteer their own bodies in the pursuit of science. Our panellist Sir Mark Walport has continued in this tradition of self-experimentation, and has with him x-rays of his own faeces for show and tell!Producer: Melanie Brown Executive Producer: Alexandra Feachem Researcher: Olivia JaniBBC Studios Audio Production
