You know, as humans it's hard to not fear the unknown, as in, when an earthquake will hit and what will the ramifications be from the earthquake. But yet, you still are told to go on living without fear of the unknown. I personally don't worry about stuff like that, and I know there are people out there who freak out over it, especially when it happens. How do you guys feel about the unknown and how do you prepare yourself, or not prepare yourself for it?
