Question for sys: when I'm walking the Montana prairie and my eye catches the movement of a rattler raring up to strike and I instantaneously jump out of the way...is that instinct from some sort of genetic evolution that humans are or should be afraid of snakes? I mean it seems silly that humans are generally afraid of snakes and spiders and such, even though most species are not dangerous to us. Hell I've jumped at a mouse running across the floor. Basically I'm a pussy right?
