“Smell is a form of communication between partners - people respond to the smell of their partner,” added Carl Philpott, an honorary consultant at James Paget University Hospital in Britain.
A lot of my patients who lose their sense of smell say they feel a lack of bond with their partners, Philpott added.
This may be because we are drawn to people who have a different set of immune genes from us - an evolutionary mechanism to encourage us to pass different immune genes to our offspring, Jacob explained.
