It's time to reconsider the notion of organisms designed solely for human-centric applications, as we have much to learn from bacteria and their roles on this planet.

Bacteria and viruses can manipulate our bodies, which is why our defense mechanisms, including homeostasis, are crucial to prevent infections and maintain health.

Microbiota are not only present in the gut but also in the mouth, nose, and skin, and they play a crucial role in our overall health by forming a dense and complex ecosystem that interacts with our body.

There are trillions of healthy bacteria in the gut that are very active and have many roles beyond digestion, including regulating blood glucose.

The microbiome, an ecosystem of healthy bacteria in the gut, governs the gut-brain connection and plays a crucial role in mental health.

Exposure to microbes from the environment is essential for educating our immune system and maintaining its balance.

The universe is approximately 13.8 billion years old, providing ample time for random events to lead to the emergence of life.

Microbiomes tend to exist in stable states, making it difficult to dislodge them from their current condition, even after significant changes like antibiotic use.

The gut microbiome consists of trillions of microorganisms throughout the entire digestive tract, not just the stomach, and includes communities in the nose and on the skin, which are beneficial for our hormonal health, brain health, and immune system function.
