Dr. Adele Bergin:

As Professor McGuinness said, we do not have a great grasp on all this. One of the things we mentioned in our opening statement is that overall life expectancy in the South is two years higher than in the North. We cannot say exactly what is driving that. We know it is a whole range of factors combined, from income to access to the health service, equality of the health service and access to education. That shows more the outcome, that there is this gap here, part of which goes back, potentially to what the Senator is talking about.
