I've heard/read from a few sources that it is very important to wash hands after urination, because Coliform lives on human skin everywhere from the belly button down to the upper thighs.
I'm confused, because I searched and couldn't find any information about E. Coli living on skin, and it seemed to contradict further declarations I've heard by some that the bacteria can be quite poisonous if it leaves the intestine, internally.
Could anyone confirm this? Why wash hands after urination, if you only touch your genitals for a few seconds and you don't touch any urine? Are all of our bodies really a toxic waste lining in the midsection? If so, HOW? What makes my skin so friendly to this 'deadly' bacteria? And why is it not living all over the rest of our bodies?
This topic has been driving me nuts lately, as I'm totally clueless.
Pardon if it belongs in the microbiology forum... I felt it was slightly more fitting in this one.
