Why are some of you people scared of spiders?

Ummm Is this a serious question!?! Why are some people NOT scared of spiders???? I know I am terrified because of the simple fact that they can kill you but also because they can jump on you and crawl away so fast that you'll never find them and you can spend hours worrying If It's still on you or near you! There's clearly no need for any more stating of the various reasons!!!!
