Thats an interesting idea but to me that just seems foolish. I'm into taking that much risk just to get a rush. The risk I prefer is to do something meaningful. Building infrastructer, rescuing those in need, protecting soldiers on the ground, that kind of stuff. To me adventurous means trying things that haven't been done before in order to find out if it is a better way to get stuff.
High risk just in order to do high risk stuff isn't as interesting nor part of an adventurous life to me. I do however understand why others would want to do those things and find it ironic that they can't legeally do it the land of the free and brave. They need to take a trip to places like socialist europe in order to engage in their sport legally, guess that illuminates some of our priorities here.
