I don't know about proud of it, but lots of injuries... that's just comes along with going at life full tilt. I'm not sure I ever met anyone that was into the attention aspect, aside from the rare chronically ill person who made that their outward identity. But that's not injury.
What are they doing that leads to so many injuries?? My friends, my partner, and myself... we're mountain biking, open ocean sailing, camping, and working on our boats. Picking up some wounds is inevitable. One of the corollaries of Type II and Type III fun is being prepared for unpleasant shit to happen. Most people I know who are going farther afield like this actually push the limits to test their skills and preparedness.
