Deu no New York Times!
"The typical human is home to a vast array of microbes. If you were to count them, you’d find that microbial cells outnumber your own by a factor of 10. On a cell-by-cell basis, then, you are only 10 percent human. For the rest, you are microbial. (Why don’t you see this when you look in the mirror? Because most of the microbes are bacteria, and bacterial cells are generally much smaller than animal cells. They may make up 90 percent of the cells, but they’re not 90 percent of your bulk.) "

Amazing, no?

I was a bit shocked when I first read that fact (it was in a National Geographic article, a few years ago). But I breathed a sigh of relief when my Biology teacher told me that we "only" had about a pound worth of bacteria on our body.
