Touch

Touch is the sense that makes us human. If you are born blind or deaf, your body and brain will mostly develop normally and you can live a rich life. But deprive a baby of social touch and they will have higher life-long levels of stress and fear. From why brushing fingers with a waiter will make you leave a larger tip, to why a hot drink in a job interview improves your chances, this is a mesmerising journey into our senses. With surprising stories and cutting-edge research on pleasure and pain, it shows how touch shapes our sense of self and bonds us together.
