Want to feel happy on your commute to work? Well, yeah, I guess you could listen to that Pharrell song over and over again while you white knuckle grip the steering wheel. But here's a simpler way: ride a bike.

new study says that bike riders have the happiest commutes, followed by drivers, and, not surprisingly, public transit riders.

So ditch the car, burn your Metrocard, and start pedaling. You'll be doing something good for your body and the environment.

Which in turn makes me feel better about using so many paper coffee cups each morning.
