You want long life right? You would rather exist for many years. So as such does it not make sense to take the time for a simple exercise such as bicycling? Offering up a wonderful workout and viewing things differently. Certainly the initial start up is rather steep dependent on what you are looking for. Once the bike is purchased the long term benefits becomes clear. A low impact exercise, the wind in your face and the views to see. To ride is to exist, and why not exist a long time?
