Interesting Fact - Population

According to the Population Reference Bureau, about 107 billion people have lived on Earth.

(They calculated it using stats and guesses from when Homo sapiens first walked the earth, about 50,000 years ago, and assumed that 50,000 years ago there was a population of 2.  I bet there was a humdinger of an argument about that statistic.)

How many people have ever lived?
