Suggest that you obtain and read the book
Sharks and Survival by Perry W Gilbert , HC, D.C.& company, Boston,n 1963, LCCC # 63-22519
You just might change your mind about sharks and Underwater Attacks-- You are the very first person who dives in California I have ever heard of seeing a GWS up close and personal and survived to tell the tale.

With all due respect to Bill, he's not exactly in exclusive company there:
From Catalina Island, 2014 -
As of 2009, this guy had been solo urchin diving the Farallones since 1978; as far as I know if anything took him out of action it was the hep C he discusses in the film -
We've had a few passing white shark encounters where I am in South Florida lately as well:
Frankly, I think the best precaution against getting hit by a shark is to keep your eyes on it. In the case we've been discussing, the first hint the woman had that there was a shark around was being bumped. At that point there's not much you can do. Sharks didn't get where they were by being stupid; a ~6-ft prey item that sees one coming might decide it's not going down without a fight.
