Here's something you'll never be able to forget: next time you lean in for a kiss, keep in mind you're transferring and receiving millions of bacteria. How romantic!
A group of scientists from the Netherlands asked 21 couples at an Amsterdam zoo to participate in the study. The couples had their mouths swabbed before and after sharing a kiss, and researchers examined the swabs for bacteria. (Video via YouTube / Bart Weber)
According to the study, published in the journal Microbiome, an "intimate kiss" lasting 10 seconds transfers an average of about 80 million bacteria. The researchers had one member of the couple consume a probiotic yogurt drink to measure the transfer, so they could identify the specific bacteria found in the yogurt.
