It's not who used it, we all supposedly only use 10% of our brain's capacity. Search it up. Now if this is a typo and you meant 100% the answer is nobody in real life as the such of using 100% of your brain means more blood flow is needed, meaning you need a bigger heart, resulting in needing a bigger body, bigger lungs. Or perhaps just a more efficient body. But in answer to who uses only 10% of our brain, well that's just a myth, but it is us humans.
we use only 1 or 2 %
stiffen Hocking use 1o & of his brain
