This post is from BuzzFeed, showing that in 45 years there has been almost no change to life expectancies in sub-Saharan Africa. Nowhere else in the world have health conditions remained unimproved for so long.
GapMinder has a stunning graph that plays life expectancies by country. Select almost any sub-Saharan country, hit the Play button and watch how these countries have stagnated or worse, regressed. My favorite degenerate African country, Zimbabwe, has a life expectancy that plunged from 62 to under 45 coinciding with the reign of President Robert Mugabe.
I suppose that there will always be some segment of the world at the bottom of the pecking order; I just wonder if this part of Africa is destined to remain there forever. Certainly during these rough global economic times their future looks even more uncertain.
