When her mother suddenly passed away, Eva Holland began to examine the extent to which her many fears had limited her and wondered whether it was possible to move past them. This sent Holland on a deep dive into the science of fear: Why do we feel fear? Where do phobias come from? Can you really smell fear? (Yes.) What would it be like to feel no fear? Meeting with scientists and individuals to help her answer these questions, Holland records her findings in Nerve. A refreshingly accessible, sometimes funny, rigorously researched journey through the science of facing our fears.
