In the 1950s, there was little regulation about coastal releasing of slaughterhouse waste. So tiger sharks were attracted to the shore. Regulations are better now, so you see fewer of them close to shore.

On the other hand, if large sharks such as tiger sharks are declining, there may be more black tip sharks, which are among their prey.

Well, if you take the view that Tiger [Woods] is going to win two every year that leaves only two majors for the rest of us.

We all grew up watching Jack and what he achieved. It was a record that was untouchable. And now Tiger is coming. There are a few people cursing their luck now. You have to beat Tiger. If he stays fit and healthy . . . can he achieve the impossible? He's on his way.

There's a few people cursing their luck now. But you have to beat Tiger. If he stays fit and healthy ... he has 10 of these majors now, and we all know Jack had 18. Can he achieve the impossible? He's on his way.

'Blue' is out there with the sharks.
