To me, this is an interesting example of how we aren't very rational in assessing risks in general.
Whether this person meant, "I lived through something that should have killed me, so I'm now living on borrowed time and it doesn't matter when that ends," or, "Nothing I can do has the same potential to kill me that that earthquake did, so I won't worry about it," his reaction really isn't rational. One random, high risk event has no relationship to the other, non-random and controllable event. "I've lived through the worst life can throw at me, so bring it on," is not a rational attitude.
On the other hand, as Peter observed, the cenote tours, which are a form of "doing a cave dive to try it" have an extremely good safety record, so if that's what he was talking about, he wasn't talking about a high risk event.
And as Marci observed, cave divers are not extreme sport people. In fact, I remember someone writing that, when he actually began to meet some, he was disappointed to discover that, in general, they're rather anal, risk-averse, boring sorts. You won't find cave divers sporting Mohawks and leaping off snowy cliffs! It's an activity where virtually every move is pre-planned and choreographed, and there is little room for spontaneity or improvisation. It's kind of the "anti-extreme" sport
