Research shows that the gut and brain are connected, a partnership called the gut-brain axis. The two are linked through biochemical signaling between the nervous system in the digestive tract, called the enteric nervous system, and the central nervous system, which includes the brain. The primary information connection between the brain and gut is the vagus nerve, the longest nerve in the body.
The gut has been called a “second brain” because it produces many of the same neurotransmitters as the brain does, like serotonin, dopamine, and gamma-aminobutyric acid, all of which play a key role in regulating mood. In fact, it is estimated that 90% of serotonin is made in the digestive tract.
Here is where science finds the greatest difference between male and female of the species. While the brain and the gut are two strong influencers, a women’s common sense is more likely to overridden by her heart. In the male, brains, gut feelings and common sense will definitely be overridden by their strongest influencer, their genitals.
This is science folks. I don’t make this stuff up…
