Now, before you panic about the many diseases you’ll contract from all these bugs, rest assured. In other words, it’s an understatement to say that the number of microbes we contain is astronomical. And it’s 100 times as great as the largest estimate of the number of stars in the Milky Way galaxy. That number’s greater than the estimated number of human cells in our bodies. Though I knew about the bugs that inhabit my digestive system, British science journalist Ed Yong helped me understand just how numerous and widely dispersed those microbes are on my body-and yours. Most of the rest of us find that surprising. If you’re a physician, a nutritionist, or have studied biology, you’re probably aware that our bodies contain an immense number of microbes.
