The Science Behind Fear

"we are born with the only two intimate fears: the fear of falling and the fear of falling and the fear of loud sounds." I feel like if you were born without fear it would be really cool to hangout with the person, they would actually do anything. I understand how it could be dangerous and probably not safe for the person but it would be really cool to experience for a bit maybe but not for their whole life. I feel like fear is important to keep us safe and like it keeps us in the limits, without fears people would be doing some really dumb stuff.
