We’ve written about race in sports before. That’s actually where this whole thing started unraveling for me.
There’s a statistical discrepancy in the skull size of black people and others: they’re smaller. There’s some debate as to what it means and if there is even a discrepancy at all. Let’s just assume for a minute that the African brain is smaller on average than other brains.
Why is that important? Because with our brain entropy model, this smaller-skulled race would have an athletic advantage. Especially in “fast twitch” events. Because the engine is smaller, it takes less energy to start, and therefore can start quicker.
White people can’t jump. If you assume that the more entropy you have in the brain, the slower the time perception, smaller brains would be much more likely to jump higher and run faster.
Faster recovery. If we also assume the brain is made of the same substance, this smaller brain would also cool off faster when overheated. Another advantage in most sports.
Less sleep. If sleep cools the brain, a smaller brain would mean less cooling, and less sleep necessary to zero out entropy from the day. We’ve explored this concept before.
What about all those great distance runners from Kenya? I’ll just put this here. 
But also, this race has a much greater risk of death by stroke or heart attack. How does that relate? A stroke happens when your brain pressure gets too high. For smaller brains, higher pressure is easier to attain. So the same mechanism that gives them an advantage at sports, increases their risk of early death.
Assuming that the African brain is smaller, we can predict most aspects that set them apart as athletes as well as their sleep patterns and elevated risks of heart attack and stroke.
