When asking for directions, you should look for someone with a good sense of smell. That is the advice of scientists who have found that people with a naturally good sense of direction also have a heightened ability to detect faint odours. Brain scans revealed two specific regions of the brain that are heavily involved in the control of both skills. Veronique Bohbot from McGill University in Canada led a team of scientists to determine if there was a link between the two very different traits. A group of 57 volunteers participated in an experiment which assessed the proficiency of their nose as well as their sense of direction.
