Which body structure is a powerful generator of emotions, gives you a sense of direction, and serves as a cannon all at the same time? It’s your nose, of course! It is common knowledge that without our noses the scent of a rose could not give us joy, nor would our food taste like very much. Less well known is the fact that our noses are directly hooked into the brain’s limbic system. Your limbic system plays a central role in generating and controlling emotions. This is why certain scents are able to raise strong emotional memories in us.
