The new are you worried about sharks when you dive went live today, and as always (unless someone's realllly quick) I got the honour of casting the first vote.

I'm almost ashamed to say it. I had to answer "sometimes". Despite seeing Mike Rutzen talk at the London Dive Show and despite compiling numerous statistics on shark attacks I can't help but sometimes look over my shoulder when I know I'm diving in an area with sharks.

It would never, ever stop me diving - and I love seeing them, I really do. I just get pangs of it sometimes. Can anyone else relate to that? You're diving and you just get an urge to look over your shoulder to see what's watching you!

What kind of sharks have you seen? Is some of your video online? I'd love to see it!
