They say that seeing is believing but as far as we’re concerned, the most potent of the senses has to be smell. Think about it; smelling freshly baked bread will get your mouth watering before you’ve even stolen a glimpse of the sourdough, the scent of your mum’s perfume will comfort you before she’s given you a hug, and smelling the flower that grew outside the Airbnb on your first girls’ holiday will instantly transport you back. Smell is the king of the senses – many of our most important memories are tied to scent, whether it’s the body spray you doused yourself in at school or the bedding in your childhood room.
