I think a lot depends on where you dive - in Jupiter, in Palm Beach county, for instance, there are sites its almost a given you are going to see them. And for me, its a privdlege.
Candidly, attacks on divers are rare, for a variety of reasons, and the sharks we as divers are most likely to encounter tend not to be agressive - even Carib Reef's and Bull Sharks in the case of spearfishing want the fish - they generally don't attact the spearfisherman.
I'd be much more worried if my travels put me close to a great white, or oceanic white tip!
I think sharks are on the mind of most divers - especially new, or less experienced - If I need to swim an anchor down to hook a wreck, solo, its on my mind, I'll admit.
I think its correct to address the subject, b/c its on their minds - but getting too hung up I think is counter productive - I know "you" can be the one - but honestly - how many divers are attacked and killed by sharks in a given time period - a miniscule number - I'm sure someone will correct me, but I don't recall any in the last year or so, at least in the USA.
