If the top three are 89.52, 84.74 and 84.6, then how can UK be number 33 with our life expectancy at 84.74? It's the same as Japan...

I wonder if diet and related obesity have an impact on life expectancy? There seems to be a huge rise in obesity in US and UK. And the lack of fresh fruit and vegetables, which figure in the Mediterranean diet, must be a factor.
The Japanese eat lots of fish, which is supposed to be excellent for health.
Interesting Donuel. But will people change their habits, or just carry on doing what they do?
