Manipulation

There is a article that says germs in our gut manipulate us.Manipulate is a pejorative word, and not really true in this case. When your guts feel better it makes a genuine difference. We have a very important nerve from the gut to the brain, the Vagus nerve and it connects the intestines, the heart, and the brain. A set of organisms that makes your gut feel better sends that signal along to vital regions and we feel better as a whole. We have to make friends with these bacteria since they provide vital services to us as we do for them. Let's just call it a fair deal for both sides.
