I just want to mention briefly that I agree with your point entirely. In fact, we are engaged in what we call a joint consortium on school health, dealing with the whole range of health behaviours in schools, including the issue of physical activity.
Of course, from a federal government perspective, we don't have responsibility for what goes on in the schools, but we certainly participate in that forum, and use it as an opportunity to provide some information and some of the research results we have, and just try to play a helpful role in trying to encourage that sort of thinking, so we can make some connections.
I'll just mention briefly one example that I find very exciting, called the walking school bus idea, where seniors help children walk to school. The children are provided with an escort to the school, which deals with the safety and security issue, and it also deals with the physical activity needs of both the senior citizens and the children. So it has benefits from a number of different perspectives.
There are ideas like that, which some communities have tried, and we think it's very important to evaluate the impact of those interventions and, once we have a better handle on how they work, to share that knowledge and information with others who might be interested in trying something like that in their communities.
