The study also found that the bacteria in our soles survive longer than those in other places, because when we walk, the soles are often stained with new dirt, which provides convenience for breeding more bacteria.
The study also found that bacteria on the soles of our soles live longer than bacteria elsewhere, because when we walk, we often get new dirt on them, making it easier to grow more bacteria.
