One of the oldest modes of modern transport, the bicycle is now been seen as not only a healthy alternative to the automobile, but a means to combat global warming, while at the same time as a possible antidote to the high cost of gasoline. Because of the public perception of cycling as inherently healthy and also as a very environmentally friendly means of transport plus its increasing cost advantages over gasoline fueled vehicles bicycle use has increased over most of the developed world. Throughout the nation, the number of people bicycling to work has increased 43 percent since 2000. More cities encourage residents to recognize the benefits of using their bikes for transportation. Limit yourself from watching The Tonight Show and cut back slouching from your couch and go biking. Biking is a great way to include your daily workout in your routine, and it's a lot cheaper than a gym membership.
