"When I get up from my chair, ten times more bacterial cells get up than human ones," says Dr Bruce Birren.
He is one of the hundreds of US scientists involved in the world's most extensive map of the microbes that live in and on us.
The Human Microbiome Project has catalogued the genetic identity of many bacteria, viruses and other organisms that live in intimate contact with us.
They are not germs that need eliminating but a fundamental part of what makes us human, researchers say.
Yet until recently, little was known about the identity of trillions of the microbes populating our bodies.

Interesting, and a bit creepy.

Billions, trillions, of little microbes in my tummy and *elsewhere* 
saying, "feed me" or "get me the hell OUT of here!"
Too cool. Another way I heard this put is that we're 90% microbe and mite - only about 10% genetically human. We're aggregate entities. Collective beings. Vast communist conspiracies. 
And now, kinda itchy vast communist conspiracies.
