If you don’t have the creepy crawlies, yet, just wait until you read this! New research suggests that the human body has about 1,000 species of bacteria on the epidermis. One thousand different species! Certain areas that are more “moist” (like the belly button and inner bend of the elbow) have up to “10 times as many bacteria per square inch compared with” the dryer areas, like the mid forearm.

What this means is that bacteria can not only be a good thing, it’s also essential to our health.
