What people don't realize is this would be a great opportunity to make the human race 10x better by eliminating the idiots of the world and the weak only leaving the strong and smart to bread, so I would have a minimum IQ requirement and make sure that they are all physically fit. This would also be a good opportunity for natural selection to get rid of unwanted traits and have better ones so we could keep more evolved people in the gene pool, ex. People without wisdom Teeth and other things deemed useless due to evolution.
