I have wondered about this quite a bit in my life. It seems like some of us are really risk averse, and others will simply jump in and do anything crazy just for the experience. I am definitely the latter. I have certainly stuck my hand in the fire both metaphorically and literally.

Maybe people like us are naturally primed for deeper exploration of reality. It takes a level of fearlessness to look at ourselves and delve deep into the unknown territories of our minds. Perhaps that natural inclination to not trust has more to do with a need to see for yourself rather than just going through life acting on blind faith!
