Only using 10% of our brain, psychics and Father Christmas
So I ran into this nonsense again, someone saying that we only use 10% of our brain. *Sigh*. To anybody who actually sits down and thinks about it for a while, it is obviously false. For example, how many times have you heard of somebody having a stroke, in the part of the brain they don't use and therefore being unaffected, or how many times have you heard of somebody having a brain injury, but being unaffected by it....
