Alright, so picture this: you’re just chilling, minding your own business, and you probably think of yourself as, well, you—a human through and through, right? But here’s a mind-bender that might make you say, “Whoa, wait a minute!”

Did you know that your body is actually home to roughly the same number of bacterial cells as human cells, and sometimes even more?

Yeah, you read that right! For a long time, the popular figure you’d hear was that bacteria outnumbered our cells by a factor of 10 to 1. Recent, more precise research has actually brought that ratio closer to about 1.3 bacterial cells to 1 human cell, or even a roughly 1 to 1 ratio if you’re comparing cell nuclei. But even at that closer estimate, it still means you’re walking around with a bustling metropolis of microscopic life that’s just as numerous, if not more so, than the cells that make up you! We’re talking trillions upon trillions of these tiny guys living pretty much everywhere on and inside you—your skin, your gut, your mouth… everywhere!
