I agree with you. I have good gut bacteria.
Question. Who did all that counting? :)
It was such a daunting task that it was only finally done about 10 years ago by some scientists with incredible patience. But that was such a huge breakthrough in research that now there are gut flora surveys going on around the world, and they are learning all sorts of things.
While still relatively in its infancy, it is pretty obvious that this is going to be a huge area of research and discovery.
