Matt: I suppose it is scuba diving?

　　Todd: Oh, nice! Well, tell us about scuba diving.

　　Matt: Well, I haven't been for awhile because I have been living in Japan and it's expensive to do it here, but when I was in Thailand I went scuba diving quite a lot. I did the PADI certificate. I just love it. I did quite a bit of scuba diving both in the Gulf of Thailand and the Indian Ocean and saw whale sharks, leopard sharks and all sorts of things.

　　Todd: How do they compare, the Indian Ocean and the Gulf of Thailand?

　　Matt: Well, the Gulf of Thailand is quite polluted and there is a lot of shipping thatcomes up from Singapore to Bangkok, whereas the Indian Ocean, it's called the AndamanSea but it's part of the Indian Ocean is a lot cleaner but it can be affected by monsoons.

　　Todd: OK. Great. Thanks Matt.
