In this episode, we answered listener questions. We talked about our amazing bodies and how they work. Our skin has three special layers, and the top one protects us. When we're sweaty, some things can stick to our skin because of the sticky sweat. We also learned that inside our bones, there's a special place that makes blood cells. These cells do important jobs like carrying air and fighting germs. And we learned that we are still trying to discover how the very first life started on Earth.
