My mum, (who in fairness was told this by her mum) told me that Black people couldn't swim in their adult life. She said that their bones get heavier as they get older and that's why you don't see any Black people at the Olympic's (& other swimming comp's) etc. We all believed her, until I brought it up to my best friend when I was about 16, who happens to be mixed race... The sheer look of disbelief on her face.... "Man! My mum told me that!"
