Jim Hatfield of Lytham is a man on a mission. In March of this year he lost his wife Anita to Idiopathic Pulmonary Fibrosis, a lung disease she fought for three years. Jim cared for his wife throughout that time as she progressively deteriorated because of the condition. Today we are attempting, with the help of Jim, to walk in Anita's footsteps - shining a light on the harsh realities of lung disease.
