Silver lining of the global recession? Decreased shark attacks

This is really neither here nor there, but it’s got a sort of ring of truth to it. It seems that the frequency of shark attacks on popular vacation spots decreases before and during economic collapse. I’m thinking that maybe it’d be just as effective to analyze air travel records or hotels, but this is much more fun and macabre.

The professor who brought this up suggests that attack frequency could possibly predict economic calamity as well. Well, it’s a good excuse for economists to visit Florida, at least.
