In this episode, Health Journalists Helen Thomson and Cat de Lange explore the surprising brain superhighway between scent, emotion and memory, to explore why certain smells can yank you back to childhood and why smell could hold the key to healthy brain aging.  They are joined by neuroscientist Michael Leon, who explains what happens when we lose our sense of smell, and staggeringly that simply enriching your life with  pleasant scents could help protect you from diseases like Alzheimer’s.
