To what can we attribute a phobia? What exactly happens when we feel fear? Such are the questions threaded through Eva Holland's Nerve: Adventures in the Science of Fear, her courageous chronicle of many years spent facing down two debilitating phobias - of losing her mother and of heights. By taking part in innovative pharmacological and exposure therapies, interviewing some of fear science's leading scientists and simply jumping out of a damn plane, she found that fear lost much of its fearsomeness. Eva discusses her book with Ben Goldfarb. Visit auntiesbooks.com/event for details.
