Why You So Liddat is a show that explores the mind, our behaviour, and why we are the way we are. There are many myths that surround left-handers - that they're more creative, that they find it harder to read maps, or that they live 9 years shorter. However, research over the years has managed to separate fact from fiction. Right-hander Clare Porac has studied left-handedness extensively over the years and wrote a book about it called Laterality: Exploring the Enigma of Left-Handedness. She gives us a hand in understanding the science of handedness.
