Fear is one of the strongest forces that drives and motivates us. It's an emotion that can cause people to go to lengths and do things they would never have dreamt about. So the question is: what are people afraid of? What do people fear most in the world? What can make people go insane with how frightened they are of something, or what can cause people to do impossible things to get rid of it? I asked 10 people what they're greatest fears are to see what can cause the strong emotion in other people, and this is what they said.

1. Bugs and heights

"Insects and heights terrify me — even roller coasters." — Zainab Nabi, 16, @zainabnabi10

8. Merging

"Switching lanes!" — Michelle Ifarinde, 17, @michelleifarinde

After talking to these people, I realize that fear lives within of us at all times. Even everyday, mundane things have the ability to scare us, such as bugs or switching lanes while driving. Other people have deeper fears, and think about what really affects them, like the fear of failure. But most fears are completely rational; the fear of death or terrible things happening. It's something we can all relate to and take comfort in the fact that we all share the same concerns. I learned that a person's worst fear can also tell a lot about them. It shows what they value the most and what they don't want to lose, and it can even show their morals and values as a person or what they've learned from past experiences.
