But if the movie "Open Water" and other animals-on-a-rampage movies have you terrified of all creatures great and small, these tips could help. They're from The Worst-Case Scenario Survival Handbook.

• First, if a mountain lion attacks, size matters. So, open your coat to look wider, or put a child on your shoulders to look taller   which also, of course, makes the child look bigger.
• Then, if you're attacked by killer bees, run in a zig-zag pattern, or run through tall grass or weeds to disrupt their flight pattern. But don't dive into the water thinking you'll escape. The bees will track your air bubbles, and sting you every time you surface.
• How can you protect yourself from a bear attack? They can probably outrun you, but because of their weight, bears can't climb trees as high as people can. Bears also hate surprises. So when you're hiking in bear country, wear bells on your belt, and let 'em ring.

So, what's the animal most likely to take a bite out of you? Your very own dog or cat. A study by Northwestern University found that over half of bite victims were chewed by a pet they knew. Mostly their own animals. Half of the bite victims were hospitalized, and a third required surgery or had permanent damage, like missing fingertips and severed nerves. So, when do most bites happen? When owners try to separate two fighting dogs--And the top trigger for being bitten is reaching for the dog's collar. What should you do instead? Either yell out your pet's name very firmly, grab a hose, or drag them away by their hind legs.
