Your tripping example is incredibly patronizing.
I crashed my motorcycle years ago and have mild but still lifetime injuries. As a result, I've changed my behaviors and have put away my motorcycle. It's given me a place to reflect on what my own life is about, where I want to go, and the pain my family felt when they heard about the crash.
I choose the attitude of learning from the past and adjusting my behaviors.
I had a similar experience on my bike and chose to get back on, though it certainly took me a while, and I've stopped riding in weather and in other conditions. My family supported me in my decision. I guess you and I are just wired differently.
I try not to share my cynicism with the world too broadly because I think our modern era has too much of it. I think humanity is advanced by the wild dreamers.
