The Human Body Is Mostly Bacteria
One of the biggest discoveries about the bacteria on the human body is that they exist everywhere. The average human being carries about 10 bacterial cells for every one human cell they have. That means that you’re mostly bacteria if you just go by population! Almost all of those bacteria are much smaller than our human cells, but the fact that they’re present almost everywhere we look means that they probably play an essential role in many aspects of how the human body works.
