A study by the National Institutes of Health says about 1,000 different kinds of bacteria thrive on the average human’s skin, the Los Angeles Times is reporting.

Some live only in the armpits, while others prefer only the forearms or navels. Scientists say they believe the bacteria are helping our skin, but they’re not sure how.

“We live in a microbial world, and these things are not all out to get us,” said a specialist who wasn’t involved with the study. “You don’t want to live in a sterile world. You probably can’t live in a sterile world.”

This explains why my skin always feels like it’s crawling.  And I thought it was because my neighbor is a perv.

I wonder if the skin bacteria have a pecking order: Do bacteria that live only on the forearms think they’re better than the armpit bacteria?  I’d think so.

I just hope none of my skin bacteria decide to go to war against any of their neighbors because I’m still dealing with acne.
