+100 on everyone's opinion!

most important to least important:

* steady drop in weight, definitely in better shape
* feel fully awake when arriving at the office; less need for coffee
* faster commute than car/public transport
* use to need 1/2 hour to find parking at work, and another 1/2 at home too
* have saved a TON of money on gas/car expenses
* better understanding of the community where I live and work since I get to actually see it!
* feel and am more sociable since I frequently stop and chat with other cyclists/commuters, something I would have never done while driving or on public transport.

the only downside is that most businesses don't have bike stands or don't allow bikes inside, and with the rate of thefts rising dramatically, I can't really shop at larger department stores and tend to shop at small grocery or convenience stores where I have a good view of the bike.
