As a white man I agree with you.
Blacks also have denser bones than other races, are less likely to suffer from bone disease, and spend less time in the womb but emerge more physically developed. They learn to walk and run faster. Blacks are also more genetically varied than other races.
But there's another side to this. Isn't there always?
What separates man from animal is his intelligence. Only in that one trait is he distinct from and does he dominate the animal kingdom. In all others such as strength, speed, penis size and agility animals surpass him. Cheetahs are faster, gorillas stronger, horses larger endowed, leopards more agile, etc... etc...
Consider how little time animals spend in the womb - a lot less than humans - yet can walk almost as soon as they are born.
Blacks, because of their physical nature, are closer to animals than other races.
