Let's see, I separated my shoulder on a fast three wheeler ATV. Then with my arm in a sling, I rode it again to have the same thing happen again. Both times I knew what could happen. I took ultralight flying lessons on a whim. Oooh, I can fly! I walked through downtown Chicago during midnight by myself through a really bad area that was having riots at the time. I thought that was interesting and entertaining!

Just to name a few off the top of my head. LOL
