Your sense of smell helps you appreciate the little things in life, like the aroma of your favourite foods or the fragrance of flowers.

It can also act as a warning system, alerting you to danger signals such as a gas leak, spoiled food, or a fire.

A loss in your sense of smell can harm your quality of life and can also be a sign of more serious health problems, a new study has warned.
