Why Do We Feel ‘Anxious’ Before Important Events?

Imagine you're about to go on stage and perform a magic trick. Your heart starts beating fast, your hands feel shaky, and you can't stop thinking about what might go wrong, that's anxiety! It happens because your brain is preparing you for something important, like a big test or a speech. You feel it in your body, but it’s all part of how your brain helps you stay ready for the challenge ahead.
