Bet you didn't experience wildlife like this when you were on your last wildlife safari. Marlice van Vuuren is a Namibian animal conservationist and a woman very familiar with the ways of the African cheetah. She should know, her last 34 years were spent growing up around animals in Namibia, and she currently runs the N/a'an ku sê Wildlife Sanctuary with her husband Rudie.

It's that sort of experience that's prepared her for this close interaction with wild cheetahs, no doubt mixed with a healthy dose of bravery and maybe a shred of craziness. Check out this video where van Vuuren gets off of her dirt bike and walks around among the wild cats, often advancing towards them and showing her dominance -- it's a pretty amazing show.
Unfortunately, the clip appears to be spoken in English, then dubbed in French, so here is a translation of what Marlice Van Der Merwe is saying about her encounter:

If I lower myself down to their level, they'll approach as we appear to be be of similar size ... I'm doing this to show how cowardly they are, not to tease them ... But also, to get a rush of adrenaline ... As soon as you turn your back on them, they attack ... As soon as you look them in the eyes, they're afraid of you ... If you run, you're prey. But, if you turn around, they stop ... I think they've had enough
