All I know is that ever since I started riding daily I am a much happier and relaxed person. The ride home gives me a chance to leave the day behind and center myself. I enjoy it and I stay fit and healthy. I get to learn new things and meet people I never would have had I not started riding. I'm also doing my part to cut down on pollution.
So you ask what's the point, will it make a difference? To me riding makes all the difference in so many different positive ways.
