I know you were working in government 10 years ago on this issue.

I- it's a really good question, and, and I think that the interest has been there for a long time, but that the n- the necessity, uh, the burning platform's even greater.

Um, so to take i- in turn the challenges to how to get this on the agenda, uh, and then what some of those solutions might be, I think one of the challenges public health has and prevention has is that the, the levers are very, very broad.

Um, the, the levers for improving the public's health do not just live in the Department of Health and Social Care at all, and in fact, many of the bigger levers don't live there.

Um, and the timelines are, are unclear.

So the greatest benefits that we'll see from many of the public health interventions will be, uh, will, will, will occur far after this government has left office.

Now, not all of them, and if you take any smoking, any of the smoking cessation, uh, and smoking public health impact, we tend to see, we tend to see those improvements in public health pretty quickly, but the greatest impacts are over time.

And then secondly, why do we struggle so much with this kind of cross-government approach to change? 'Cause on the face of this, this is not complicated to drive, right?
