But since all the blacks have developed in the last few centuries are major epidemics of diseases caused by monkeys, they have not been able to develop civilizations.
Because of this, most blacks in the past few centuries have had to live like cavemen, so basically, almost all physical work all day to survive.
The ones that went to civilized nations? Slaves, therefore still all physical work all the time.
TL;DR: Blacks are only physically stronger on average because it's all they're good at.
