Wow. Some of the comments in this thread regarding bugs and animals that the posters encounter actually make me glad I live this far north. The worst I have to deal with is the occasional wasp that flies a little too close for comfort when I'm sitting still for any period of time, but they never do anything so they're pretty easy to just ignore.
Some people are just afraid of some things. No rationality behind them. Could be some deep seated connection their brain subconsciously makes. Just ...phobias. *Shrugs*
Fear from ignorance is what irks me.
That's actually the case. It's known as "Preparedness Theory." It basically means that way back in our evolutionary past, we encountered a lot of dangerous things like poisonous animals (snakes, spiders, things like that) so the individuals whose brains developed in such a way that they learned things like "Stay the hell away from this scary-looking snake!" a lot faster than others tended to survive and reproduce more. Over generations, this became hardwired into our brains so that we learned these things faster than other things. In people who have irrationally strong phobias of, for example, harmless insects that look vaguely like the dangerous, poisonous ones, it's this evolutionary preparedness misfiring and overgeneralizing.
