They say the left part of your brain is what makes you good at math and the right side is responsible for creativity. I'm going to go ahead and call bullshit.
For a long time now scientists have been getting away with passing theories, backed-up by their fellow scientist colleagues, with "credible" documents that other (would you believe it) scientists have verified.
Let me throw some truth your way. What is actually going on in the human brain is: the left side of the brain is for filtering out news about Donald Trump, while the other half is dedicated to funk.
It is therefore rather obvious which side of the brain this Jacques Renault ditty activates.
