The speaker emphasizes that humans are largely composed of bacteria, which play a crucial role in our health. These bacteria serve as a protective layer, aid in digestion, produce vitamins, and train the immune system to fend off harmful microbes. Despite their vital contributions to our well-being, they often go unrecognized.
can you summarize this for me.
"So I know you think of yourself as human beings, but I think of you as 90 or 90 9 percent bacterial. And these bacteria are not passive riders. These are incredibly important. They keep us alive.
They cover us in an invisible body armor that keeps environmental insults out so that we stay healthy. They digest our food. They make our vitamins. They actually educate your immune system to keep bad microbes out. So they do all these amazing things that help us and are vital for keeping us alive, and they never get any press for that."
