Skydiving, done right, is not a coin toss of survival. It is definitely in the category of things I would have done before I was married, along with flying lessons. I get that people are pulled to the thrill of the challenge. What I don't get is why the dismal survival rate doesn't push them back.

If you want to know if an activity is dangerous, just look at how insurance companies view them.
I've never tried to underwrite anyone who disclosed skydiving as an activity, but it's definitely something that they inquire about.
