Just like in the 100 metres final, it's all about those African genes. The top spots go to South-west Africa, west Africa and North Africa. The Dominican Republic also gets an honourable mention. Although not located in Africa, I'm willing to be it has a large African expatriate population. Otherwise, how could such an outstanding performance have been achieved?
Native Swiss are simply unable to compete with the south-west Africans whose crimes surpass them more than twelve-fold. Picture it as race: before the average Swiss completes one circuit of the track, he will have been lapped 12 times by a South-West African.
