Episode 17
Everyone has either a left or a right side of ones brain that is more dominant. it is said that if it is your right you are usually more imaginative and intuitive, but if it's the other way around however, you are more likely to be more logical and analytic.
Something amazing to add to that is that if you are a person who is considered to having a left dominated personality your right half will check up on the other half every 90 second or so.
