It turns out there are a lot of women who still have the instinct to jump on a table and start freaking out when they see a spider.  And . . . there are a decent number of guys who would join them.

According to a new study from The Telegraph out of Ohio State University, up to half of women and one-in-six men admit they've got arachnophobia.

The study also found that when people have a fear of spiders, they think spiders look bigger than people who aren't afraid of them.

So if you're afraid of spiders, when you see one, you think it's gigantic . . . even if it's not.  And that makes the fear even tougher to overcome.

I am only afraid of spiders if there is more than two of them. Are you afraid of spiders?
