People Who Can't Feel Scared

Some people have a rare disease that stops them from feeling afraid. This happens when a part of their brain called the amygdala is damaged.

One woman with this condition, known as SM, was studied by scientists. They tried to scare her with scary movies and animals, but she felt no fear. She even wanted to touch snakes and spiders!

This disease shows us why feeling fear is important. It helps keep us safe from danger. But for people like SM, they might get into unsafe situations because they don't feel scared.
