Pheromone parties are the latest strategy by the lovelorn to find soul mates. Attendees contribute a T-shirt they’ve slept in overnight, and the worn shirts are then sniffed by prospective partners, according to Time magazine.

Although Time didn’t provide any statistics on the success of this tactic, pheromone parties are growing in popularity across the country. Evidently, they might be a better way to find a partner than odorless online dating. Researchers have shown that humans use their sense of smell to determine if a potential mate has compatible genes for healthy offspring.
