Humans are full of bacteria
Not so much of fun it sounds! The human body is, in fact, a bacterial house. It was recently reported that there are 100 billion bacteria in the human body.There is also a popular myth that there is actually more number of bacteria in a human body than cells. But, it hasn’t yet been verified nor disproven. The smell from the belly button of a person is also due to the presence of bacteria. There are 5 pounds of bacteria in the digestive system of a human body alone. However, most of the bacteria in the body are in fact useful. So, they are mostly there for a good reason.
