Is big-wave surfer, and shark-riding freediver Mark Healey crazy? Or does he know something the rest of us don't?
A little of both, I think, as this video of Healey diving with bull sharks attests. He goes on from the title quote above to say: "People have ulterior motives. I think people are way more dangerous than sharks." Hard to argue with that.
This guy, however, seems more than a little crazy.
This guy, too.
