Long considered our most "beastly" and primal sense, the inner workings of smell have stumped scientists for centuries. Now, in THE FORGOTTEN SENSE, Jonas Olofsson uncovers the sophisticated biological processes that animate our olfactory system, with profound implications for how we perceive the world around us. The sense of smell has long been underappreciated. In a 2012 survey, adults were asked which sense is the most important, and only about two percent chose the sense of smell. In another survey, Americans were asked what is most important: their sense of smell or their pinky toe. The result was a tie. However, attitudes about the sense started to change after the coronavirus pandemic hit. Since 2020, over 300 million people have suffered from an impaired or distorted sense of smell after getting Covid. People began realizing, at last, the importance of this forgotten sense. Indeed, our sense of smell guides our lives far more than our screen-heavy, sight-privileged era would suggest. It animates our experience of food and drink, helps us access memories, and strengthens our intimacy with each other. Drawing from cutting-edge original research, Olofsson shows that not only is our sense of smell extraordinarily sensitive, but also how it engages our brain's full capacity. From the pheromones, environmental signals, and emotions we process with each breath, olfaction makes us the individuals we are. Moreover, smelling is an intellectual exercise, Olofsson argues, one that we have the remarkable capacity to strengthen and, with some effort, even regain after illness.
