Question: What would happen if humans used 100% of there brains.

Humans actually do use nearly all of their brain! It’s a very famous myth that we only use 10% of our brain. A famous philosopher once said that most humans only fulfill 10% of their potential, which might be true. Our brain does have a massive ability to learn, for example some people can speak 10 languages, but most of us spend a lot of time just relaxing, watching tv or playing computer games and not concentrating on learning new things. However, all the bits of your brain are there for a reason, at this very moment my brain is thinking what I am going to type next, reading the letters on the keys and making my finger move to the right one, while keeping me breathing and listening to the music in my head phones all at the same time. The brain is an amazing and very busy thing, there is no way we could live using only 10% of it.
