Is everyone scared of something?
I’d assume so, fear is the natural response of our bodies.
It’s, if I’m not wrong, what kicks the “Fight or Flight” reflex into action, now whether that fear is reasonable or not is a different story.
I mean, there is a phobia about a duck watching you.
And even the most fearless people have something they are afraid of.
So I’d say yes, everyone is scared of something.
