Had two shark attacks here this year. I would say putting yourself in a cage *for* the shark is you being the bait. There are other ways to get thrills...like jumping from a high height from a bungy. Try something else.
That being said, if you ever have the desire for thrilling scuba diving and are near the Andaman Islands, I have a good friend who owns a diving school(for beginners or experts) who can teach you the ropes. Bastard's motto is "Why didn't you just stab it with your dive knife?" in response to a diver coming within close perimeter of a Great White.
Good luck, Ben, but don't do it.
