If ever I want to evoke my childhood, it's smell that instantly takes me back. The powder puff on my grandma's dressing table. The leather seats in my dad's car. The hint of nutmeg in the macaroni cheese my mum made when I was poorly.
Smell is the most nostalgic of the senses and a shortcut to memory. Rip up the map, I know this way home like the back of my hand.
