This fact gets me every time. For every human cell that makes up your body, there are 10 cells of bacteria living on your body. Here’s another one – there are more bacteria in your intestine then there are people on earth. So in sum: your body is just plain full of bacteria. Its insane.
There is no feeling like loneliness in the micro-world.
I found this movie that perfectly illustrates the fact mentioned above and shows the effects. Enjoy ;)
