Answer 1

Your body is like a superhero with a special alarm system. Sometimes, it can be too sensitive and overreact. Imagine it’s like a superhero seeing a friendly kitten and thinking it’s a big scary monster.

As you grow, your superhero body can sometimes get more sensitive or change, and it might start to react to things it didn’t bother with before. It’s like your body’s alarm system becomes too cautious and thinks something is dangerous even if it’s not. So, it’s your superhero body trying to protect you, but it can make mistakes sometimes.
