Hm , from my history with simulation sickness pushing through was the only way I could really get used to it . Although it would mean going to bed sick as hell a couple of nights . <| sep |> Out of all human populations , only 5 ish percent of the variation is found between populations say , Northern European and Ethiopian and about 95 percent is found among those populations . That means of all the people in the world , 95 % of the genetic variation is shared between them . So no , no biological anthropologist would say there is a genetic foundation for race concepts . <| sep |> Hard question . It ' s like asking what ' s the best dance performance you ' ve seen ? There ' s so many different ways to answer . Your TJ vs . Barao example is great because of the expectations coming into the fight . It ' s one of the best upsets ever . I have a couple fights that come to mind that fall in the Quick Clean Flawless Victory category Lyoto Machida ' s MW debut against # 5 ranked Mark Munoz . First round , Lyoto lands two hard body kicks , two hard straight punches , stops a takedown , then KO ' s Munoz with a headkick . Machida was not hit once . He also showed incredible respect to Mark after the fight . Demian Maia vs . # 4 ranked Carlos Condit . First round , Maia absorbs one jab , grabs a singleleg takedown , cuts through Condit ' s guard , gets the back and slowly sinks in the choke like a python . It took less than two minutes to finish the fight . These types of quick , clean , flawless victories over top 5 fighters that exhibit methodical and precise skills are what I think of when I think best mixed martial arts performance .
