I love to read these posts. It seems all of us who cycle-commute are seemingly alone amongst our co-workers. But after checking this thread, we are apparently not so rare as we are made to believe. "Crazy" is not a term for people who do not follow the crowd; it fits someone who, when faced with reality (such as the real benefits of cycling vs. the dangers of not cycling) continues to believe the falsehood.
I hope I never go back to depending on sitting idle behind the wheel of a car while my blood pressure is shooting through the roof. I look forward to living (hopefully) 20 years longer than average and enjoying them with full vigor until the end. I also hope to convert others along the way!
In conclusion, we cyclists must be doing something we love. We couldn't be doing it for popularity.
