A Kiss Transfers 80 Million Bacteria

Got plans to kiss under the mistletoe? Think again! Recent research published in the journal “Microbiome” found that as many as 80 million bacteria are transferred during at 10-second French kiss.

The research was quite thorough. Scientists recruited 21 couples who happened to be visiting a zoo in Amsterdam. As part of the study, the couples were asked to engage in a 10- second kiss with full tongue contact and saliva exchange. All in the interest of science, of course!

On a side note, researchers found that many of the men embellished the frequency of their romantic encounters. For instance one male volunteer claimed he averaged 50 kisses per day, while his partner said they only kiss 8 times per day. That’s 42 kisses unaccounted for. Oh oh!
