I am trying to introduce a new category named Biology in which I am going to resume some interesting facts we learned at the university. So I hope that I am not writing any non-sense or so. If it happens, please don’t beat me.
Our teacher in Immunology, who has developed his own website at http://www.immuno.info, told us the number of microorganisms on and in our body. Now, what would you answer if I asked you how many of these little things like bacteria and all the rest are on our body?
The answer is 10^12 microorganisms are living on our bodies’ surface! But this is nothing compared to the number living inside of us: 10^14. How many cells have you got as an own organism? 10^13. The good thing: The vast majority of the bacteria living inside of us are good ones, which we need for our own metabolism or which are entering in competition with the bad ones to take away any space where they could develop.
