I have always believed, and taught my children, (as well as those who have asked of me) that fear is a natural experience and a choice, and easily overcome by gaining/exacting knowledge.

Or, in cases where the knowledge is not evolved nor available, to consider not choosing to be arrested by fear. Though I may someday, I have not experienced, either my self or by association via another, anything that can not be overcome by gaining knowledge and/or accepting a humble position in light of knowledge, unknown.
