I don't think I'm the best person to answer that, since I don't have all those numbers. But I do think physical inactivity is a worldwide problem. The top countries are those with good physical education systems in their schools.
Unfortunately, most Canadian provinces have dropped physical education in favour of computers. They have also done away with home economics classes, and that may have been a mistake.
I have often heard provinces say that there isn't enough time in the day for physical education. In Manitoba, however, all students take physical education every day. So it is possible.
In my view, that is what we should once again be aiming for.
