Show me which bacteria you left behind and I will tell you who you are!

Beware! Don’t leave a bacterial fingerprint behind you in a “crime scene” or elsewhere!

Your skin is more than what you think it is. Even if you don’t leave a “visible” fingerprint on my laptop monitor, on your car windows, or anywhere else, you are leaving millions of bacteria there. What’s new? We all new that our fingers are a wonderful niche where invisible bacteria thrive?
What IS new is that these bacteria are highly diagnostic too. Tell me which bacteria you left behind; I tell you who you are. Thus claims a paper by Noah Fierer and coworkers from Colorado…
