really? If you had an island with 1000 boys and 1000 girls don’t you think eventually people would have equal advantage and would have to figure things out to make it work equally? Even if some were fat, ugly, poor, a bit less religious, more religious, etc… they would have no choice but to eventually settle and if they didn’t there would be an equal number of boys and girls single. Presumably there are boys and girls both with advantages and disadvantages equally from a mathematical standpoint or at least close.
Since there is not an equal number single please do the math and realize that is a numbers game and all other factors are not relevant. Yes there are older boys but many many more older girls. Of course if you understand the age cap concept fully it would be clear anyway. Why is clear elementary school mathematics so hard for people to wrap their head around? I do not work for NASI BTW or even know who does.
