I fell off my bike a few months ago. No idea why; wasn't paying attention. Before that, I hadn't fallen in a few years.

Thinking about this recently I made a list of all the reasons one might fall; collisions, mechanical failure, whatever. I have fallen quite a few times over the last 40 years, and when I listed them, they were all my fault, albeit to varying degrees. I've hit road debris of all kinds, sometimes with bad results. I've hit animals, and I've been hit by animals. I've run into a pedestrian. And I've run into a car. I've collided with other bicyclists... at least three times, and in every case I could have prevented it had I been more vigilant.

For all the digital ink we spill about cars, I have never been hit by a car.
