I want to point out that YOU claimed that "more than 100% percent of differences in life expectancy" were explained by those 3 things. When I had pointed out other stats that meant early death and added several others that explains a huge part of those differences and the maximum that you could have been able to explain is 100%.

And you claimed that an study about public services planning applied to the whole economy of a country. So it is YOU who either doesn't understand studies or who is simply lying.

Yes, I do understand data. That is your problem, I'm not ignoring the facts and data that refute your claims. And again, you haven't even given the definition you apply to call private healthcare "more productive". It is almost as if you want to distract attention... go figure.
