Watch | Finding true love in the armpit

This 'Sweat Shop' in New York is allowing customers choose partners basis body odour. The idea stems from the science of pheromones or chemical signals that animals send out to entice mates. The dating service mails people t-shirts, they wear them for three days without wearing deodorant and then they mail it back. They are then cut into swatches and sent out to other participants. They smell each one and you let 'Smell Dating' know which ones they like. If someone likes the same person too, the service gives out both parties contact information.
