Discovery’s Shark Week (starting July 31) is one of our favorite weeks of the year. Despite all the studies proving excessive TV deteriorates your health, it’s the one week we’ll couch-it, glued to the screen, lapping up hours upon hours of sharks. Sharks on the hunt, sharks attacking people, sharks in their natural habitat, endangered sharks, big sharks, little sharks, even the weirdest sharks. So what’s the big deal with sharks? Watch. Find out. Become addicted. The count down begins now.
