Africans Crowd The Bottom of The Life Expectancy List

According to the CIA's world fact book, more people of African Descent around the world and particularly in Africa live shorter lives when compared to other ethnic groups.

In some African nations the life expectancy is only 31 years. While Asian nations fare far better with life expectancy well into the 80's.

It is also a known fact that the U.S. spends more on health care than any other country but according to the CIA world fact book (out of 224 nations) it ranks only 50 (78.11 years) in life expectancy.

And according to the Census Bureau and domestic numbers from the National Center for Health Statistics, Black Americans have an average life expectancy of 73.3 years, five years shorter than white Americans. Black American males have a life expectancy of 69.8 years, slightly longer than the averages for Iran and Syria and slightly shorter than in Nicaragua and Morocco.

Curiously, the rates of Cardiovascular disease, Diabetes and Renal Failure are also much higher in people of African descent living in the west (particularly in nations who participated in the Slave Trade). The reasons for this are not clear - since the same effect is seen independently of socioeconomic status.

Also, curiously, African American families have a tendency toward smaller birth-weight, which is known to be associated with shorter life expectancy, and CVD, RF and diabetes (particularly type II).

The smaller birth weight indicates that there may be something more fundamental going on - that potentially there may be some heritable effect which has not been identified.

It's my personal belief that this may be epigenetic (wikipedia that word, and you'll get a definition of this - in short it's things that you inherit, but which are not DNA).
