      Hmmm! I don’t know, I guess we use less than all the brain, I think we only use a small bit at anytime, so maybe 10%

      I think it’s better to think about how we use our brain rather than how much of our brain we use. I think it might be misconception that we are only using a small portion of our brain. Really most parts of the brain have a function so we are using all of it, but we might not be using it very well. We should try and stimulate our brain by learning new activities and hobbies 🙂

      The brain is responsible for lots of things that we don’t even think about consciously, for example breathing. Pretty amazing really.

      Probably all of it but at different times. The unconscious brain is thought to be governed by about 2 thirds of the total brain. This just leaves 1 third for our conscious minds. This is interesting because it means that the majority of our decisions are probably made automatically, and we therefore have much less control over our decision making than we would like to think 🙁
