Doctors travel to the home of Sinead Mills and Jason Mooney in Tallaght, south Dublin. Both long-term smokers, the couple admit to lighting up in the house, but they are also concerned that the diet of their two sons - ages 12 and 13 - is not up to scratch. As well as that, the entire family could do with some more exercise according to the visiting medics, who remain in their house to oversee the changes that could have a positive effect on the household's health.
