Dr. Warshawski, you made comments in your opening remarks about childhood obesity costing us $7 billion a year.
I hate to put this in economic terms, because these are our Canadian children, and one would think that making sure we're taking steps to keep them healthy would obviously be the top consideration. I'm just wondering, in terms of our health care system, which has been under such pressure lately, if we were to implement a lot of these obesity-fighting measures—stop the marketing to children and provide better physical activity and better nutrition, etc.—what the economic impact of that would be, say, a generation down the road.
