Tiger Shark Encounter

I have always had great respect for the people who research sharks. There like an elite group of fearless human beings. They will do just about anything to get a shark to come near them. The guy in this video just has on some swim shorts, and he's filming 2 giant tiger sharks that are only a couple feet away. That's just to risky to me, one mistake and the shark sees you as food, sorry bud but your a goner.
