I’m wondering how much our sense of smell plays a part in who we are attracted to. I’m not talking about noxious bodily smells or perfume. I’m talking about a person’s individual smell. This is something that online dating can’t provide. You may have matched with the ‘ideal’ human being virtually, but when you meet, the attraction just isn’t there. Equally it can work in the reverse too. Smell can trigger emotions and it can warn us of danger. Is this the true Chemistry .
