In the dropping dead from heart attack stakes it would seem living in the band from North Africa, through the middle East to the former USSR, gives you the greatest chance of not seeing grandchildren, with having lived under the hammer and sickle the most likely to see you expire face down in your porridge.
The US is surprisingly low on the danger list (139th), a shock considering how many Yanks qualify for their own zip-code.
The two coconut guzzlers are Sri-Lanka and Papua New Guinea (94 & 65 respectively for heart attacks) mid table where most of the nations fond of them reside.
So, heart disease and coconuts don’t seem to corollate, as to what does, fewer hours of TV watched is a strange contender, amount of world heritage sites in your country (contra-indicator) or the more perceived corruption and fear of your government, all are.
I would imagine that a good quality sitcom, a visit to a nice castle or garden and not considering that the knock on the door could be the thought police coming for your fingernails would all lower the stress on your heart, but I suspect there is probably more to it than that.
