Just random: Probably these women are far more healthier than other women around the world. Just check the statistics of the sicknesses caused by over-eating (basically being fat), smoking and drinking. These women neither smoke nor drink nor eat fast food. Everything they eat is far more organic than what most women around the world eat.

Probably they are also fitter than an average woman around the world, since they will have to first hunt then eat teir food and hunting it down or finding the right fruit in the trees etc must be time cosuming and they will have to move the whole time.
