In fact, the reason is that although black people do have unique advantages in physical conditions, not everyone does. Most of what we usually see is screened out on the screen. In fact, black Americans are in poor health, but black Africans are not like this. We may find that some black people we see in America are very strong.
Some star players even reach several meters, and the men in black you see are so strong that everyone must think that annoying people are like this. In fact, some historians have said, why are American blacks much better than African blacks? In fact, it is because he can board a slave when he sells slaves. In fact, he is very strong, so his descendants also have certain genes. Another reason is that, in fact, the living standard in the United States or the Americas is much higher than that in the African continent, and the fitness atmosphere in the Americas is not comparable to that in other places, so the blacks in the United States are extremely strong.
The social environment in America is much better than that in Africa. The American people eat well and live a very rich life. The rising life of African blacks does not satisfy you. Their food and clothing problem has not been solved so far.
