> I wonder if a lot of these people have some issues that cause them to seek the adrenaline and other hormone rushes from these activities. Everyone has a different calculus of what risks are worth it. I don't think it's fair to characterize them as "issues." Skydiving is dangerous, but not ridiculously so-- about a 1 in 100,000 chance of dying per jump, though this does wobble a little bit on your preparation and where you choose to jump (places like Lodi are disproportionately dangerous). One way to understand this order of magnitude is that you're spending a few hours of life expectancy per jump. I was into airplanes; the fatal general aviation accident rate per hour is about the same as the skydiving risk per jump. But I loved the feeling of being in the air, the things I saw, and the way it felt to control an airplane. This meant on a day with 5 hours of flying, I "spent" much more life expectancy than someone who skydived once. I went into it open-eyed, and I'm glad that I have the experiences of having flown.
