Most of the bacteria associated with humans is good. There are relatively few bad guys that are out there. So now we are completely reversing our thinking about bacteria, one of our health defense systems. And this is where all these hard wired health defences are really changing our conception of what it is that we're able to do. We're starting to look think about health less as this passive state that, you know, we get to enjoy until fate crushes it with some unfortunate disease and then we got to go to the doc.
