You are actually retarded lol. It's not genetic. You probably think that African runners are faster because of genetics.

Wrong dumbass. There was a study done that proved that the only reason Kenyan and Ethiopian long distance runners are faster is because they train harder and with longer intensity. Not genetic whatsoever.

Edit: It's very easy to overestimate the role "genetics" plays in someones success. You will quickly realize genetics are negligible. People being good at anything has always come down to what they put in. You reap what you sow.
