What power do smells have?

Many people don't consider their sense of smell particularly important. However, if we had to give up one of our senses, surveys show that the majority choose their sense of smell. Twenty-five percent of the students surveyed would even rather lose their sense of smell than their smartphone. But we would lose more than we realize. Smells not only evoke memories, they also warn us of dangers and illnesses. They have power in our everyday lives. And we haven't yet fully explored this power – the potential of our sense of smell. It could also help us solve future challenges.
