HTDE: Crushes and Smells

This episode of 'How to Do Everything' by Wait Wait... Don't Tell Me! blends lighthearted advice with scientific curiosity, beginning with a heartfelt story from a former teen reporter reflecting on a 1999 incident involving a teacher's death and the lasting impact of youth journalism. The show then shifts to a playful yet insightful segment where 10-year-old Darcy seeks advice on how to tell a boy she likes him—Aiden—only to reveal in a follow-up that he has already confessed his feelings. The conversation evolves into a fascinating discussion with Claire Dumarc, a researcher at University Paris-Saclay, about why certain smells seem to linger in the nose long after exposure. She explains that smells are molecular particles destroyed by enzymes in the nasal system, making the 'phantom smell' a neurological phenomenon rather than a physical one. The episode also explores the universal appeal of vanilla, linking it to breast milk and early childhood nourishment. Throughout, the hosts blend humor with genuine empathy, offering both practical advice and surprising science.
