Intelligence is largely genetic (though it can be improved slightly by putting in maximum effort). However this consideration becomes tricky when looking for someone to make babies with. The hottest people are usually dumb as rocks, while the most intelligent people are usually fat and socially awkward. This goes both ways for men and women. This means ukizaa na mtu hot cake, dumbness is in your children's future, na ukizaa na genius, ugliness and awkwardness is in your children's future. However as we all know, beauty is very helpful in life and brains too. How do you choose between the two?
