Do satellites eventually fall back to Earth?

Certainly! Here's a possible questioner's tone description, based on the given paragraph: "Hey there, I've been wondering about something for a while now. It's about those satellites that we send up into space for various purposes. You know, the ones that provide us with GPS navigation, help us communicate, and so on. But I've heard that they don't stay up there forever. Is that true? Do satellites eventually fall back to Earth? If so, what causes them to do that? And what happens to them when they do come back down? I'm really curious to know more about this. Can you shed some light on the subject for me?
