For the most part, I'm not a person who craves a lot of excitement. Others may go for extreme stuff like skydiving or bungee jumping, but they're not really my idea of a good time.
Sure, I understand perfectly why they're appealing if you like that kind of thing, but the only time I really like being scared is when I'm watching a horror movie. And no amount of safety equipment will make me relaxed about the experience.
For some people, though, it seems that this safety equipment makes the whole thing too boring. Based on the way they handled these situations, they might think it's way more fun to see if they can put the parachute on mid-air.
