ELI5: Explain Like I'm 5

Microbes and Man

Man and microbes have a special connection. Microbes are tiny living things that can't be seen with the naked eye. They live all around us, including inside our bodies. They help us in many ways. For example, they help us digest our food, fight off illnesses, and give us vitamins and minerals. In return, humans give these microbes food and a place to live. Together, man and microbes work hard to keep us healthy!
