thanks for the links to the diets. These are aspects I never knew before.  
Funny you should send one that mentions the Masai. As a little girl LOOONG ago 
I 
 unwillingly spent a summer in Nigeria. Nigeria was  plunged into civil  war. 
 I lived every moment in my Campfire  uniform because I had  missed summer 
camp over this war. When my father's work was done  he took  us all on camera 
safari to east Africa.  I  proudly wore my Campfire  girl uniform as we visited 
each tribe saluting them with a WOHELO!
 
And then we entered a Masai village on our way to visit an old drinking  
buddy of my dad's. I saw a man in a lion's mane head dress with his wives and  
wives'  herd of cows. My father's friend explained that he was a MAN  because 
he 
had killed a lion, I decided from that moment that when I grew  up I would 
kill a lion and become a man.
 
Well I never did but I did become an anthropologist. This  is fascinating. 
Thanks again.
