I love scuba diving. It is so amazing to just drop into the ocean and see what's down there. The colours are amazing, and it's amazing when you finally do a deep dive (above 30m) the feeling of freedom that you get. I thought it would be scary as I'm not a fan of heights, but being under the ocean is different because it's so quiet and you fall slowly, not quickly like on land. It's really peaceful under the ocean, unless a speedboat comes by, and the fish get bigger the deeper you go.
No, we've never scuba dived, but have only done a tiny bit of snorkelling, the goalies were always not a good fit, or they leaked, so we just gave up.
I got an ear infection from 1/2hr pf snorkelling off a Gilly Air island, off Lombok, in Jan '95. After I took some (Dr prescribed tablets for 3 days, it was better.
