In recent years, the likes of Tinder, Match.com and PlentyOfFish have taken the physical interaction away from dating and reduced to it to a series of, well, phone messages and the like.
However, a new service that's opened in New York by a group of artists is aiming to change all that. The aptly-titled Smell Dating claims it's the world's "first mail odor dating service" and has a specific set of rules for those wishing to take part.
You pay a one-off fee and are then set a t-shirt which you're instructed to wear for a period of three days without deodorants, perfume, aftershave or anything that can take away from your natural musk. You then pop said t-shirt into an envelope. A few days later, the sender will then receive TEN t-shirts from various people and based on their smells, they'll determine who they like.
What's interesting about the service is that it doesn't even specify the gender or sexual orientation of the wearers, believing that people should follow their instincts - and nose - on what they're attracted to. It might be a bit gross, but it does have some roots in scientific fact. In fact, the service have included an interesting reading list on the topic of olfactory senses and attractiveness that base it even more in science.
So far, the service is being piloted in New York, however those behind Smell Dating believe that its members "make connections via deeply intuitive cues, perfected in the ancient laboratory of human evolution."
