Unfortunately at the population level, the majority of the population are overweight or obese and the majority of the population are inactive, the message here is that health gains could be made at the population level if sitting time was reduced, of course, in addition to engaging in regular exercise.

I think that's what will make a more convincing case to schools, parents, etc. that this is going to lead to improved learning and a greater learning experience and ... that this is the way to go.
