A reminder of the unparalleled advances in public health made by communist states. Even if every absurd fabrication that the anti-communist propagandists like to parrot about the millions supposedly killed by Stalin, Mao, etc. was true, those numbers would pale in comparison to the number of lives they saved, the hundreds of millions of life spans extended by entire decades. And if you want the perfect control sample of what it looks like when you start with nearly identical conditions but don't have communist central planning, look at India.
You realize two of those countries are also socialist right?
Also include the declines in life expectancy in Bosnia+Herzogovinia and Albania after the collapse of socialism and reintroduction of capitalism.
