I'll jump in with a little alternative perspective:
After the Corps, I was traveling around climbing a lot. Until bad accident almost killed me. Wind River Range. Lumpy Ridge. Half Dome. Devil's Tower.
I didn't do it to talk with non climbers about it. They're not impressed, and usually think you're crazy.
I did it because it's a freaking amazing rush.

A few days later:
I was actively searching for the rush I got in the Corps. It's pretty hard to replicate, and if you find a way to do it, it's not gonna be safe.
Being dropped 54 feet by a knot-pass mistake by my belay cured me from trying to replicate the rush.
Mostly.
