A successful re-mount!
After taking the tumble, cursory testing by pressing and prodding ruled out any possibility of broken bones. Just that the right hand was a little painful. I was more afraid that if I packed up and went home, I will have an insurmountable fear of coming back.
After a couple of minutes of rest, went back to the spot and kept trying. Obviously I was inordinately afraid and focused on not falling again. The first three attempts, I aborted before re-mounting. Succeeded with the fourth one eventually.
Here is the first successful re-mount.
