Why Commute by Bike?

I introduced my commuter bike the other day, but I realized I haven't mentioned why I commute by bike.

• Financial Freedom.  Biking to work allows our family to save money.  We've only had one car since early 2009.  We "upgraded" to a slightly larger/newer car (ie minivan) in 2010 - and paid cash.  My bike cost money, yes - but a bike is cheap compared to a car payment!
  
  
•  Health. I get paid to sit at a desk all day (except when I go to meetings - then I'm paid to sit at a table).  Without some form of exercise, I would turn into a baked good.  Biking is easy because it doesn't take that much time out of my day - my commute biking is about 20 minutes whereas my commute driving is about 10 minutes, so I get 40 minutes for the price of 20. 
  
  
• Productivity/Creativity.  Days that I bike are often more productive and/or creative days at work.  Endorphins win over coffee.  I still have coffee... but I don't need it quite as badly!
  
  
• Biking simply feels good.  My 20-minute commute is a good wake-up in the morning and helps me de-compress in the afternoon.  My family notices a difference in my mood when I bike - I'm much happier coming through the door than when I drive.  I get time to think about things, but also some time to just be outside and enjoy it.

When was the last time your commute did these things for you?

(Note to my wife: Yes, you can remind me of this post when I'm feeling lazy in the morning.  I won't appreciate it then, but I'll appreciate it later!)
