Your stinky feet can reveal who your partner is
Science & Tech / /
Sharing your shower, your bed, your saliva with your partner means that you are sharing bacterial colonies too. That is probably the reason why you grow to be like each other. Isn’t that sweet?
This news about the extension in form of microbes of you and your loved one is a result of a recent study published by the American Society for Microbiology.
The study was based on comparison of bacterial profiles from 17 different spots on the body, including the feet, the outer nostril, the eyelid, the bellybutton, the inner thigh, and the armpit, for a group of heterosexual couples living together.
After taking samples of colonized microbes, the microbiologists created a computer model to see which areas had the most bacterial similarities between partners. It’s quite expected that those areas would be the torso or even the thigh having in mind the physical contacts between partners, but it was in fact the feet. The feet, eyelids, and back came up to be the most, bacterially speaking, similar spots.
In fact, having foot similarities with a person you’re living with is logical since you walk on the same floors. The eyelids on the other side are a bit of a mystery.
It was found that partners were actually not similar regarding the bacteria found in thighs. Results showed that those bacteria were more similar to the bacteria found on other participants of the same sex than on people you're having sexual interaction with.
Other findings of the study go just in line with previous researches on the same issue. Partners have similar mouth microbes, which makes sense knowing that a 10 second of kissing transfers 80 million bacteria. And that may be a reason your immune system looks a lot like your partner’s over time.
When you are in another room beside your home, you colonize that room with your personal bacterial too. You even share a same bacteria with your pet. And while you’re away from home, the contamination by your personal microbe diminishes the longer you’re away.
Bacteria are affected by almost every change you make in your life style. An example of this is drinking a lot of alcohol, which makes your skin a home of a microbe called Brevibacterium, which feeds with the ethanol in your sweat. Your microbiome is significantly enriched if you are an owner of a pet with which you spent more than four hours daily. Or if you are diagnosed with allergia, you probably have more diverse bacteria in your nose.
All in all, falling in love isn't just about getting to know your loved one, it even goes to sharing your microbiome with them.
