Ha ha. I bet you do David, but not withstanding your incredible analytical skills, some folks think that it’s ok to go to Hawaii and go for a swim. As much as you can’t blame the sharks for mistaking a French woman for a domestic seal, you shouldn’t blame her because she apparently swam in murky water, she’s probably not an expert on shark attacks. 
I guess I am an odd bird as I have always been amazed by the ocean and considered being an oceanographer at one point. I read a lot and read about shark attacks and conditions during attacks and feeding and what they think leads to a nibble or attack. Normally done by juvenile sharks. Man-eaters not necessarily the case. Some sharks are more prone to attacking man than others. I guess I am cautious and try to be informed. So, I know not to snorkel in conditions what could have me confused for a seal or meal... I tend to heed warnings and history. Often we are swimming with sharks and don't know they are there.
I figure if it is my time to go I will not be able to stop that event.
Darwin award winners are common, I try to not become one. Some people seem determined to become one.
It is sad she got bit, but fools often rush in where angels fear to tread. Why would you continue to snorkel in murky water? If you cannot see well in that area you move on to another area.
We all do stupid things from time to time, me included. Got many injuries I pay for everyday where I was stupid. Just trying to be less stupid...
Be it Mt Lion, Bear, snakes, bison, sharks, etc...I tend to try to understand the major things that cause them to attack or bite and try to be observant and avoid the riskier conditions. I grew up in forest nearby as a kid and spent time in nature and learned from my grandfather who was a hunter and woodsman and part Cherokee Indian.
Entitled people today feel they can do anything without consequences, they become the cautionary tales for others.
Got passed Sunday by a guy on a white liter or larger sport bike and he had two helmets strapped to the sides of the bike and he was wearing none. Saw him at an intersection waiting to turn right a mile previous. He passed me 15-20 miles faster and 1/2 mile later turned left. I doubt he will live to see retirement, but he might be lucky to do so. Riding how he did, I think it unlikely... especially in Tucson without a Hemet.
As John Wayne was quoted to have said, "If you are going to be stupid, well then you better be tough!"
