Drs' Notes: How can we train our noses?

Chris and Xand van Tulleken continue their conversation with Katherine Whitcroft, ear, nose, and throat surgeon at Sheffield Children's Hospital and co-director of the Sheffield Chemosensory Research Lab.

Together, they hear what drew her to the nose, and further explore nasal polyps. They look at nose reshaping procedures, and the medical and aesthetic reasons behind them.
