In some scary news, the latest tool for finding your perfect partner is DNA matching.
A dating service set up by biology students in Munich, Germany, is testing subjects' DNA to find the most compatible gene pools, reports the Telegraph.
The 120pounds-a-time Gmatch service uses saliva samples to test whether potential partners are compatible and claims a better success rate than any other matchmaking website.
"When we meet someone for the first time, we know within seconds whether we're attracted to them or not," said founder Sarah A. Port.
"Without realising it, the first thing we do when we meet someone is sniff them. It's all to do with the chemicals - or pheromones - that we give off," she added.
