In this episode, Bill Turnbull travels to Edinburgh to expose some of the fake news about health in old age. He meets the pensioners involved in a unique experiment that dates back to the 1940s and looks at how the results it is producing today could help the scientific breakthroughs of tomorrow. He gains access to a virtual hospital whose team monitor and treat patients - someof whom live hundreds of miles away - from a central HQ. And he explores the ways of fighting the ageing process, from the OAP gym bunnies and mediation through yoga to the ways technology is revolutionising mobility issues in old age.
