“We don’t think of ourselves as being particularly good smellers, especially compared with other animals. But research shows that smells can have a powerful subconscious influence on human thoughts and behavior. People who can no longer smell — following an accident or illness — report a strong sense of loss, with impacts on their lives they could never have imagined. Perhaps we don’t rank smell very highly among our senses because it’s hard to appreciate what it does for us — until it’s gone.”
