What does it for you most? The smell of bacon wafting through the house on a lazy Sunday morning? Or the prospect of licking the leftover cake mix in the bowl?? Hmm, let me think about that as I eat my bacon sarnie... tough call.

I'm in the studio with psychologist and behaviour expert, Dr Jane McCartney - research by Denhay Farms has confirmed that taste and smell are the most crucial factors when triggering feelings and flashbacks from our past. But why? What is it about the smell of roast dinners that transports us back those childhood Christmas's?

Dr Jane's here explaining how smell and taste is linked to those hot-spots in the brain! Smell is a strong provoker of memories and an aroma can take you back to a time when you were cooking in the kitchen with granny or mum. Out of all the senses, smell is the sense that hangs around the longest - and it gets embedded a little more so in the memory than sight or sound would, which may explain why the smell of canteen food wafting down corridors may take you back to the first day at school.
