As someone who has seen a great white shark underwater from 15 feet away (shark caging), I can safely say that there is no human alive capable of holding a great white shark still. There is simply no stopping a 20ft long, 4000lb., aquatic dinosaur. Unless you're an orca I suppose.
One of the most impressive and intimidating animals I have ever seen.
