I stumbled on this. I have taught many children and adults to ride a bike. Some of them are scared when starting out. To alleviate their fears, I bring them to a soft grassy ground and have them practice the "stage fall" which actors use: ankle, knee, hip, elbow, shoulder. It's OK to do it in slow motion. Once they do this, they realize that falling won't necessarily hurt, and they can get back on the bike and try again.

I did this with them, which inadvertently gave me practice.

Then I fell off my bike. When I got back up, I realized I was unhurt, because I had done what I had rehearsed.

This has happened several times since I taught those lessons.
