However, the word "fear" is used in another way, too: to name something a person often feels afraid . People fear things or situations that make them feel unsafe or unsure. For instance, someone who isn't a strong swimmer might have a fear of deep water. In this case, the fear is helpful because it helps the person to watch and stay safe. Someone could overcome this fear by learning how to swim safely. A fear can be healthy if it warns a person to stay safe around something that could be dangerous. But sometimes, a fear is and causes more caution than the situation calls for. Many people have a fear of public speaking. Whether it's giving a report in class, speaking at an assembly, or reciting lines in the school play, speaking in front of others is one of the most common fears people have. Some people get so scared in front of the audience that they are ready to run . People tend to avoid the situations or things they fear. But this doesn't help them overcome fear: in fact, it can be the reverse. Avoiding something scary reinforces the fear and keeps it strong. People can overcome unnecessary fears by giving themselves the chance to for some information about it, and gradually get used to the thing or situation they're afraid of. For example, people who fly despite a fear of flying can become used to unfamiliar sensations like take-off or turbulence. They learn what to expect, and have a chance to watch what others do to relax and enjoy the flight. Gradually (and safely) facing fear helps some people overcome it.
