It is dangerous. However, when you consider the economic, environmental, and health advantages it looks better. See http://www.mrmoneymustache.com/2013/06/13/bicycling-the-safe....

I feel notably worse inside a week when I stop cycling.

You know what the worst part of cycling is? The endless noise and pollution from cars.

Cars are a scourge. It is no wonder why drivers are so angry all the time. Who in their right mind wants to spend their time utterly immobilized, doing nothing but trying to avoid hitting other cars?

Cycling is always a bit of an adventure, always exhilarating.
