I wasn't mate, maybe you made an assumption about where I was coming from ?
Apologies if I wasn't clear, but the point I was trying to make that we have a below average record on preventable deaths despite a decent GDP. That not's implying a correlation, but what it does do is demonstrate that the overall wealth of a country doesn't necessarily feed through to the overall health of the country. Smoking's an example of things which cause poor health, but it's Kenshin's example, not mine, and its much wider than just tobacco, and I'm more interested in the whole picture rather than just one element of it.
People do lots of things ( smoke, drink too much, eat poorly, live sedentary lives etc ) which they know are bad for them, but they do them anyway. Some of that is because they enjoy those things, but there will be many complicated underlying issues contributing to that mindset.
To solve that, you'd have to, among other things, to use the current buzz phrase, "level up" the country, and, just as importantly, look at using more preventative measures to limit treatments needed. Both of those measures would take a long time to have an effect, and long term planning isn't something governments of any persuasion are desperately good at.
The reaction to COVID is eating up huge amounts of cash, rightly so in many ways, but it'd be interesting to see forecasts for throwing cash at making the population healthier and, given a presumably finite pot of cash, how to get the most benefit. That doesn't mean doing one thing and not the other, but like everything else in life, priorities have to be chosen.
