Yup. The gut microbiome also control our brains in specific ways. They determine what you crave and they can make you go and eat things they need to survive.

It's quite the parasitic / symbiotic relationship.

Interesting how back in the day people thought the heart was what controlled human emotions/thoughts. In the recent past that changed to no, the brain is what controls everything. It is interesting to me how scientists are now starting to realize no, most everything plays a role. This is why things pushing any sort of universal mandatory procedures are so dangerous, no one really knows the long term effects.

I'm a Christian, and I do believe we have souls. I also view the body as the tool we use to interact with this world. When the body is damaged that limits how it can interact.
