Napoleon was short.
"“Napoleon’s death certificate estimate that his height when he died was between 5’2” and 5’7” (1.58 and 1.7 meters). The discrepancy is often explained by the disparity between the 19th-century French inch, which was 2.71 cm, and the current inch measurement, which is 2.54 cm. Sources consequently estimate that Napoleon was probably closer to 5’6” or 5’7” than to 5’2”. Britannica.
He was above average for the height of French men at the time."
Yes. That's because we don't need to. Any new action or sight will be remembered. But if you see it daily you won't.
But that's not the myth. The myth is that we only use 10% and if we somehow could use 100%, we'd all be a genius, get super powers, and whatnot.
We use all of our brain but parts are used more and others less depending on the particular action.
Probably because they play with a lot of friends in a time when the cold goes around. And if even one has it...
Correlation is not causation.
