The right-hemispheric language of poetry
I took down my earlier blathering on about how I am not all poetry and flowers and once studied pure maths, because it was, well, blathering. But it really does appear to be true that poetry works both sides of your brain at once. It has been described as a right-hemispheric language (most language processing is on the left hand or "logic" side of the brain). Here is a quote from the science education review: "When you write poetry, you need to use your whole brain; both the left side of your brain (e.g., language and logic) and the right side (e.g., visualisation and creativity)". So, read poetry - it's good for you.
