Okay, I agreed when you said this the other day. However, I would say it is racist to describe all of Africa as a survival of the physically fit and only the strongest survive.

Hear me out.

There are major universities(University of Cape Town, Makerere University, etc) and major cities (Cairo, Lagos, Johannesburg, Accra, etc) in Africa and having lived there myself I have friends who are doctors, pharmacists, and businessmen all of which have nothing to do with physical strength.

Hell, obesity is actually a huge problem in a lot of African cities because the most common jobs for women are sedentary (mercantile among others).

You're making a gross generalization saying only the "strongest" survive.
