It's the only place I've ever used my Aikido. I've gone over the handlebars on my mountain bike twice and done forward rolls. I did get munched another time though but I think Aikido helped me there as well. I had no forward speed and came down roughly on the back of my head. While that sucked, Aikido probably helped because I tucked my head. I've also taken several falls playing basketball. Most of the time people don't even notice it because at this point rolling is a lot like walking to me.

I think you could argue that falling is the most valuable thing we learn in this art. It's certainly one of the most practical.
