I like skydiving and scuba diving. And in both cases I always prepare like a madman. The activity itself comes with plenty of risks, and I'm just there to enjoy it by reducing the risks best I can.
That means the blue hole can go screw itself. I'll stick to a maximum depth of 25 meters or so and my goal is to see shipwrecks (from a distance) and pretty fishies.
As for skydiving, I want a good view, no wind, a maximum of one tiny cloud, and a dropzone with good packers and craft beer.
There are plenty of people out there BASE jumping or deep-sea diving. There are plenty of them recording their own deaths. I plan to not be part of those people.
