Interesting, however, the following quote makes me suspect the researchers made the usual error of using average life expectancy, which is very distorted because of high child mortality. Would be interesting to see more precise numbers.

"Pygmies around the world are short in life expectancy as well as height, with the average adult dying at 16-24 years of age. Only 30-50% of children survive to the age of 15 and less than a third of women live to see menopause at 37."
