When you stop to think about it, you realize how amazing your body really is. Your heart pumps blood, your lungs take in oxygen, and your brain forms thoughts all without thinking about it. And while you’re aware your body’s going through thousands of processes all at once, there are a few things it does that you had no idea about.
