They're adrenaline junkies. Everyone has their own gig. I get enough rush from killing deer, so I don't have the need to jump from high places. Personally, I hate to stand near the edge of a high building or bridge. It gives me the heebie jeebies. However, about 8 years ago, I did a tandem jump from a plane at 12000 ft. The free fall was awesome. Got that off my bucket list and had a blast doing it. Wouldn't make a habit of doing it though, but it was fun.
