>>Why don't a lot of black people know how to swim? There are cultural and biological reasons for that On top of my head: 1) Bone density; african males' bones are twice as dense as white women bones, and almost 1/3 more dense than white men's bones, on average, at similar age. Higher bone density doesn't help for "buoyancy" http://depts.washington.edu/bonebio/ASBMRed/structure.html 2) In pretty much every african country, going in the water is deemed dangerous, whether in rivers or ocean, because the water is loaded with all sorts of shits starting with dangerous species. So generally speaking, going for a lethal swim for fun isn't really a thing in africa, since it tends to be rather unhealthy, and it's not new 3) Reality is also that many blacks just don't want to learn a thing in western schools, swimming being one of them
