To most people, a smell isn't just a fragrance - it's a memory. When you get a whiff of chocolate cake, you may think of baking in your Mum's kitchen. When a warm breeze blows the smell of fresh flowers, you're instantly rocketed back to your BBQ's in your grandparents backyard during summer.
And these nostalgic ties aren't just a coincidence - there's science behind why we cherish these aromas.
