I found a great website http://www.kenkifer.com/bikepages/health/risks.htm

called "Is cycling dangerous?"

The guy goes through all the statistics available on causes of death and injury and it sure looks to me that Bicycling is safer than staying in your car.

Read for yourself.

And further, bicycling is also safer than staying home and not taking care of your body.

Enjoy the website, he's done a lot of good research.
