If you form a bike habit, you might find yourself drinking less coffee and feeling more alert. Luckily for you, Denver is a fairly flat city, so a bike-to-work habit is pretty sustainable.

I force myself to get some exercise everyday, and to do it outdoors. Cycling to and from work takes a little bit longer (when there isn't traffic) than driving (although when the freeway is a parking lot, I get home much faster on the bike than I would in a car) but since I've already got my exercise in, I don't have to take time away from everything else I need to achieve, and it winds up giving me more options. But even if the only benefit I got was not having to get mad sitting in stop and go traffic, that's still worth it.
