One should never read stats without analyzing it. Take the US life expectancy of 78. It's correct, but not useful for Chinese HBGs. There is a huge discrepancy between races and people with different social economic status. For example, black males have very low life expectancy. Anyway, Asian females' number is over 90 years in the US! Even asian guys are expected to live to almost 90.

Misunderstanding stats is actually worse than not having the stats.
