Thanks, Rob. Good points. I agree that there also needs to be an overarching health goal that will pick up the positive and negative contributions of the various sectors that have impacts on health. It is ultimately good health we’re after. Interesting links! For me Portland's raging grannies were the best. I liked the guy who brought one the grannies a wooden spoon half way through. Should I be worried they weren't singing in unison (let alone harmony), or focus on the fact they were singing from the same sheet? Thanks for sharing. A.
