Author Nicola Twilley talks about the development of her scratch 'n sniff map of New York City, and about related things of interest to perfumistas: smell preferences by gender, race and geographical location, the dangers of selective anosmia, the lack of a shared language to describe smells, Sissel Tolaas' smell maps, etc etc. Almost 17 minutes; recorded earlier this month at the Gel conference ("An event about good experience – in art, business, technology, society, and life.").
