But canny bad swimmers, I'm reliably told by one IOC member.
dont know how true this is but i was told its bcos the bone structures in the ankles/feet are slightly different. meaning one is better for running and one is better for swimming.
you see, we're not all the same under the skin!!
Black people's bones are more dense and they also have a frame designed for a greater muscle mass. Hinders their performance in the pool.
