When you live life on the edge, as the Bushmen do, then baiting Cheetahs might seem to be a fun sport - as long as you know what you are doing and they don't cease to be intimidated.
The Bushmen are an interesting people. Genetically they are not related to the Black Africans even though they have the dark skin adaptation to living in the equatorial belt. Of course it is also politically incorrect to note that. Just as it is politically incorrect to note that a lot of the "Olmec" head carvings (in Central America) of boulders resemble Black Africans.
After all we know that there was no contact between continents in the prehistoric world. /sarcasm
