Feet bacteria reveals partners
Biologists have found bacteria on your feet can tell them who you live with.
Researchers at the University of Waterloo have analysed 330 skin swabs from various locations on their volunteers' skin, including the upper eyelids, outer nostrils, inner nostrils, armpits and torso.
The samples were then compared to other results from their partners, and it was found the bottom of the feet had the highest agreement between the lovers.
Biology Professor Josh Neufeld told the Mirror Online: "You shower and walk on the same floor barefoot.
"And this process likely serves as an effective form of microbial exchange with your partner, and also with your home itself."
