When award-winning reporter Paola Totaro lost her sense of smell to Covid in March 2020, her world changed and dulled in an instant. Trapped in a sensory vacuum without fragrance or flavour, she embarked on a journey of discovery to unravel the mysteries - and eccentricities - of the fifth sense.  



Our sense of smell shapes our everyday experiences in ways we often don't even notice. Its loss can transform our lives - affecting our emotional wellbeing, our relationships, our ability to interpret the world around us - and yet it has long been regarded as the least important of our senses. But Covid changed everything. As it became clear loss of smell was a key symptom and the number of sufferers exploded, olfactory researchers suddenly found themselves thrust into the spotlight, with more attention, subjects and funding than ever before. Presented with this once-in-a-lifetime opportunity, they were able at last to start unlocking the mysteries of our 

'Cinderella' sense. 



On the Scent is the story of a quest for answers, from the theories of ancient philosophers to the cutting-edge laboratories of 21st-century neuroscience. It looks at the extraordinary experiences of patients and scientists alike, offering a unique glimpse into the world of those born without smell as well as those who lose it; exploring how smell can be a key indicator of declining physical health; and offering up the latest research that can offer hope to the millions of people worldwide who have suffered sensory loss.
