Really interesting article on the National Geographic website regarding the billions of microbes that are on our skin. What I found most interesting in the article was the number of various microbes that were living on our skin, the fact that the composition of microbes is the same on both arms and varies over time depending on our environment, and that microbiologists refer to these microbes as "flora". It's a cool article that I suggest reading. I wonder what else is on our skin...
