This BBC Learning English podcast explores the connection between smell and the feeling of being home. The hosts discuss how our brains filter out familiar smells, allowing us to detect unusual or dangerous scents, and the role of smell in our limbic system's processing of memory and emotion. A quiz question reveals that 5% of the population is anosmic (lacks a sense of smell). The podcast also introduces vocabulary related to smell and the perception of home, such as "anosmic," "weird," and "out of the ordinary." Listeners are encouraged to visit the BBC Learning English website for a transcript and worksheet.
