Supposedly, a good Arabian curse is, "May the fleas of a thousand camels infest your armpits." Those fleas may have to fight for space, though.
New York University researchers believe that every person has their own personalized zoo. They discovered that not only does each of us walk around with at least 182 different types of bacteria in our armpits, but that as many as 8% of those bacteria are unknown to scientists. Not only that, but the mix of bacteria is highly personalized and subject to change over time, though there are some regulars that stay put.
I wonder what the point is of having such personalized bacteria. Is this one way we create a unique odor, or attract certain mates? Do the bacteria make us unique, or does our uniqueness attract certain bacteria? And what else are they all doing on our skin (besides being harmless)?
This is like discovering squatters in your basement - and the remnants of their keg party.
