It's a good question. When Parliament created these four pillars, to some extent I think it's a construct. Ideally, what I'd like to think about, many of the things we do don't fall neatly into any one of those four pillars. I actually like that, and I think environment and health is a very good example of that. We don't have an institute, either, of environment or health, but we do have an institute on cancer research. We do have an institute on population and public health. So issues such as environment and health, and other major issues, such as a clinical research initiative we're developing at the moment, global health research, are initiatives that transcend those four pillars and also transcend our institutes. They are championed by one of our 13 institutes, but they don't necessarily fall into any one.
So many environment and health issues are population and public health issues. Some of them are biomedical issues, some of them are clinical issues, and some of them are health services issues.
