This week's programme includes a film made by Winifred, a 40-a-day smoker
: who has been smoking since she was 11. Her husband died of lung cancer and she herself has had major murgery for a smoking-related disease. She records her many desperate attempts to give up and tests the available cures, from nicotine patches to therapy.
Will anything work? Plus diver Ian takes a camera under water off St Abbs on the Scottish coast to investigate the pollution putting him and his fellow divers at risk.
