What is the Shortest human lifespan in the world?

Answer 1

Some people suggest that:

I would ponder this being a tie between North Korea and Myanmar, yet Somalia is pushing the plunger with their piracy and the rest of the world may decide we've had enough and make the Horn glow, if you know what I mean. Not that far down the ladder is Pakistan. If you're looking close to America, most of the Mexican border towns are shooting so many people. Inside America? I'd throw it as a tossup between Philly and Chicago with Detroit, Houston and L.A. not that far away.

Zambia

However, according to the list by the United Nations (2005-2010)

and quoted by Wikipedia, the 10 countries with the shortest "life expectancy at birth" numbers (in years) are:

Mozambique 39.2

Swaziland 39.6

Zambia 42.4

Lesotho 42.6

Sierra Leone 42.6

Zimbabwe 43.5

Afghanistan 43.8

Central African Republic 44.7

Liberia 45.7

Rwanda 46.2

These are all far below the global average life expectancy at birth of 67.2 years.
