Abstract
We know that bacteria can be harmful and can cause a lot of diseases. But did you know that not all bacteria are bad? In fact, there are trillions of bacteria inside us that help us to live! These bacteria make up the gut microbiome. We wanted to understand the relationship between our gut bacteria and how we age. We found that as we get older, the different types of bacteria in our gut microbiome change. We also discovered that diseases and medication can affect this change. Knowing more about how our gut bacteria work can help us live healthier lives!
