Our senses are at the heart of how we navigate the world. Whittling this high-powered and deliciously varied palette down to just five does a great disservice to the sensory experience, Sensational argues. In fact, we could have as many as fifty-three - and they could explain such mysteries as why we kiss, in what way music is a form of emotional currency, and how a dairy-rich diet strained initial Euro-Japanese relations.

Ashley Ward embarks on a sensory expedition to answer all these questions and more. Why do women have a better sense of smell than men? Has the iPhone changed how we touch? Does the Danube really look blue when you're in love?

From the power of cuddling to what canine bowel movements can tell us about geomagnetic fields, Sensational is a surprising look at how our brains shape the way we interpret the world.
