Shark Attack Puzzler

Gentlemen prefer blondes but sharks prefer gentlemen according to the Queensland Bond University who discovered that sharks are nine times more likely to kill men than women.
Ignoring reported attacks when the shark had been provoked by people patting sharks on the head, putting their hands in the shark's, jumping on sharks and trying to ride them, 89% of attacks were on people with XY chromosone.
Now the University plan to work out why almost 9 out of every 10 attacks are on men but i think i can field that one and save them time which could be spent on more important research.
The reason why 89% of attacks are on men is because MEN ARE STUPID ENOUGH TO GET INTO THE SEA WHERE THERE ARE SHARKS, WOMEN HAVE MORE SENSE.
There you go so you can now use that research grant to look into important issues like why do men feel the need to hog the remote control and why do people continue to buy reggae records when it is obviously the same tune.
