When Jamie takes too many biology classes

Here is a funny (but very true) quote 

"By a variety of measures, the species Homo sapiens is more microbial than human. Microorganisms comprise only a small, albeit significant, percentage of the body weight (between 2 and 5 pounds of live bacteria). However, in terms of cell numbers, we are about 10% human and 90% bacterial! Further, the number of genes in our microbiome may exceed the number of human genes by two orders of magnitude, making us genetically 1% human and 99% bacterial! Consequently, bacteria play a major role in bodily functions, including immunity, digestion, and protection against disease. Colonization of the human body by microorganisms occurs at the very beginning of human life, and many of these organisms become truly indigenous to the host."

from wikipedia: There are approximately ten times as many bacterial cells as human cells in the human body, with large numbers of bacteria on the skin and in the digestive tract.

 "A visitor from outer space might think the human race is just one big chain of microbe hotels."

"The crook of your elbow is not just a plain patch of skin. It is a piece of highly coveted real estate, a special ecosystem, a bountiful home to no fewer than six tribes of bacteria. Even after you have washed the skin clean, there are still one million bacteria in every square centimeter"

"The bacterial cells... outnumber human cells by 10 to 1, meaning that if cells could vote, people would be a minority in their own body."
