Fantastic video and I have to admit that that lady feeding the sharks has more balls than I do. I have a problem with the whole idea of feeding sharks in the wild. I hope this video was made in an aquarium. I was a commercial diver for many many years and while I have been in close proximity to sharks on many occasions I believe that the natural shyness they have of human beings is your best protection. I have worked in many areas where working divers would feed fish for their own entertainment. After a few days of this they come to expect it and will become annoying to aggressive with a diver that doesn't have the time to feed them. I have had a large grouper butt me several times because I didn't have anything to feed it. A 100+ pound grouper can give you quite a butt, but I imagine it's a lot more friendly than a 100+ pound shark who expects a meal.
