I wonder what was the purpose of this Poll? What judgements can be made of people... Does it mean that Africans are the most adventurous and Asians least? Does it mean that Poverty makes People migrate, if that is so, why only Africa, and not others, after all its not like other continents dont have their Poor? And they took only the opinion of 700 million people in a about 7 billion population? Ok.. done with my asking.
